juanatsap da81a0b148 feat: iOS-specific blur bar and hide keyboard shortcuts on real mobile devices
Issue 1: Blur bar compatibility (Android doesn't always show at bottom)
 Solution: Wrap blur bar in @supports query for backdrop-filter
- Only shows on devices that support backdrop-filter (primarily iOS)
- Android devices without support won't see the bar
- Prevents layout issues on non-iOS devices

Issue 2: Keyboard shortcuts button on real mobile (no physical keyboard)
 Solution: Device detection + conditional hiding
- Added device-detection.js: Detects real mobile vs desktop browser
- Checks user agent (Android, iPhone, iPad, etc.) + touch support
- Adds 'is-mobile-device' or 'is-desktop' class to <html>
- CSS hides shortcuts button only on real mobile devices
- Desktop browser in mobile view: shortcuts button still visible (for testing)

Implementation Details:
1. Device Detection (static/js/device-detection.js):
   - User agent detection: /Android|iPhone|iPad|etc./
   - Touch support check: ontouchstart + maxTouchPoints
   - Class added to <html>: is-mobile-device or is-desktop

2. Blur Bar (@supports query):
   - Detects backdrop-filter support before applying
   - iOS: Shows blur bar with backdrop-filter
   - Android (most): No blur bar (no backdrop-filter support)
   - Prevents empty/broken bar on incompatible devices

3. CSS Hiding Rules:
   - .is-mobile-device .shortcuts-btn { display: none !important; }
   - Also hides zoom-toggle-btn and zoom-control on real mobile
   - Desktop mobile view: shortcuts button remains visible

Files Modified:
- static/js/device-detection.js: NEW - Device detection logic
- templates/index.html: Load device-detection.js early
- static/css/05-responsive/_breakpoints.css: @supports wrapper for blur bar
- static/css/04-interactive/_scroll-behavior.css: Hide shortcuts on real mobile
- tests/mjs/52-mobile-device-detection-test.mjs: Comprehensive device detection test

Test Results:
 iPhone (real mobile): is-mobile-device class, shortcuts hidden
 Desktop browser (mobile view): is-desktop class, shortcuts visible
 Blur bar: Only shows on devices with backdrop-filter support

juanatsap 2f466e46bc feat: Default to light theme on mobile devices on first visit
Implements device-aware theme defaults:
- Mobile devices (≤768px): Default to light theme
- Desktop devices (>768px): Default to auto theme
- Saved preferences: Always respected regardless of device

Implementation:
1. FOUC Prevention Script (templates/index.html):
   - Detects device type using window.innerWidth/clientWidth/screen.width
   - Sets initial theme before page render to prevent flash
   - Mobile: 'light', Desktop: 'auto'

2. Theme Initialization (static/js/color-theme.js):
   - Modified initColorTheme() to respect FOUC-detected theme
   - Saves FOUC-detected theme to localStorage for persistence
   - Prevents overwriting mobile detection with 'auto' default

Test Coverage:
- Test 1: Mobile first visit → light theme 
- Test 2: Desktop first visit → auto theme 
- Test 3: Saved preference honored → dark theme 

Files Modified:
- templates/index.html: Added mobile detection in FOUC prevention
- static/js/color-theme.js: Respect FOUC-detected theme
- tests/mjs/49-mobile-light-theme-default.mjs: Comprehensive test suite

juanatsap 2eafb78954 fix: Mobile view improvements - accordion styling and modal centering
Fixed two critical mobile view issues:

1. Extended CV Sidebar Accordion:
   - Updated sidebar.html to use native <details> element (was div with onclick)
   - Styled accordion header to match CV title badges dark theme (#303030)
   - Applied consistent styling: dark gray background, light text, uppercase, no spacing

2. PDF Download Modal Centering:
   - Added JavaScript-based centering for mobile viewports (≤768px)
   - Uses inline styles with !important flag to override browser defaults
   - Updated download button to call openPdfModal() function
   - Result: Modal is perfectly centered on mobile (0px offset)

Technical notes:
   - Modal centering required setProperty() with 'important' flag
   - Accordion matches cv-title-badges-header style exactly
   - All tests passing: accordion toggle, modal centering

juanatsap 7b60fdcf9c refactor: Separate CV domain and UI presentation models into distinct packages
**Main Changes:**

1. **Package Restructuring** - Separated mixed concerns into focused packages:
   - Created `internal/models/cv/` for CV domain logic (CV, Personal, Experience, etc.)
   - Created `internal/models/ui/` for UI presentation logic (InfoModal, ShortcutsModal, etc.)
   - Removed monolithic `internal/models/cv.go` (300+ lines → organized packages)

2. **Testing** - Added comprehensive unit tests:
   - `internal/models/cv/loader_test.go` - CV data loading and validation
   - `internal/models/ui/loader_test.go` - UI translations loading
   - All tests passing 

3. **Documentation** - Added Go learning knowledge base:
   - `_go-learning/architecture/server-design.md` - Goroutines, graceful shutdown explained
   - `_go-learning/refactorings/001-cv-model-separation.md` - This refactoring documented
   - Public documentation showcasing Go expertise (README.md kept private)

4. **Handler Updates** - Updated imports to use new package structure:
   - `internal/handlers/cv.go` - Uses `cvmodel` and `uimodel` aliases

**Benefits:**
-  Clear separation of concerns (domain vs presentation)
-  Better testability (isolated package testing)
-  Improved maintainability (smaller, focused files)
-  Scalability (each domain can evolve independently)
-  Follows Go best practices (small, cohesive packages)

**Other Updates:**
- Updated middleware security checks
- Template improvements
- Organized completed prompts

**Testing:**
- All Go unit tests pass (cv, ui, handlers)
- Server verified with curl tests (English, Spanish, Health endpoints)
- Frontend functionality unchanged (refactoring is transparent to UI)

juanatsap 810ee7955b fix: References section link corruption and download filename issues
**Issue 1: URL corruption in "See this CV in..." links**
- Bug: replaceYearPlaceholder used fmt.Sprintf on ALL URLs
- URLs like "/?lang=es" were corrupted to "/?lang=es%!(EXTRA string=2025)"
- Fix: Changed to strings.ReplaceAll("{{YEAR}}", year)
- Result: Only replaces actual {{YEAR}} placeholders, leaves other URLs intact

**Issue 2: Download filename not respected**
- Bug: Shortcut URLs (cv-jamr-2025-en.pdf) redirected with HTTP 301
- Browsers used original URL filename instead of Content-Disposition header
- Fix: Generate PDF directly in DefaultCVShortcut handler
- Result: Returns PDF with correct filename in Content-Disposition header

Files changed:
- internal/models/cv.go: Fixed replaceYearPlaceholder function
- internal/handlers/cv.go: Changed redirect to direct PDF generation

Both fixes verified:
- "See this CV in Spanish" link: href="/?lang=es" ✓
- Download link: filename=cv-jamr-2025-en.pdf ✓

juanatsap f25f2de8b3 fix: Use direct shortcut URLs in references instead of modal
## Problem
- References section PDF link opened modal dialog
- Modal doesn't work in PDF or non-browser environments
- Link was not usable when CV exported as PDF

## Solution
- Changed from `onclick="openPdfModal()"` to direct shortcut URL
- Spanish CV: `/cv-jamr-2025-es.pdf`

- Language-aware: Uses {{$.Lang}} template variable
- Year-aware: Uses {{$.CurrentYear}} for auto-updates

## Benefits
-  Works in any environment (PDF, browser, external links)
-  Direct download without JavaScript/modal
-  Shareable, permanent URLs
-  Auto-updates yearly with no code changes

Technical details:
- File: templates/partials/sections/references.html:16
- Uses shortcut URLs created in previous feature
- Maintains target="_blank" and security attributes
2025-11-20 12:40:25 +00:00
juanatsap 66e06a6cb0 feat: Add year-aware PDF shortcut URLs + Default CV modal option

- Year validation: Only current year accepted, returns 404 for past/future
- Auto-redirects (301) to: /export/pdf?lang={lang}&length=short&icons=show&version=with_skills
- Both languages supported: en and es

## PDF Modal Updates
- Replaced "Current View" option with "Default CV (Recommended)"
- Visual highlighting: purple gradient badge, star emoji , bold text

BREAKING CHANGE: API parameter renamed from 'extended' to 'long'

## Breaking Change: Terminology Standardization

Renamed 'extended' to 'long' across entire codebase for consistency:

**Backend (Go):**
- internal/handlers/cv.go (7 locations)
  - Migration logic to auto-convert 'extended' → 'long' cookies
  - API validation now rejects 'extended', requires 'long'
  - Toggle state logic updated
- internal/handlers/pdf_test.go (17 occurrences)
  - Test function renamed: TestExportPDF_ExtendedWithSkills → TestExportPDF_LongWithSkills
  - All test cases, parameters, and expected filenames updated
- internal/pdf/generator.go (2 comment updates)

**Frontend:**
- PDF-EXPORT-FEATURE.md (3 occurrences)
- doc/3-API.md (parameter documentation)
- doc/7-CUSTOMIZATION.md (examples updated)
- templates/partials/modals/pdf-modal.html (button text, URLs)
- static/js/main.js (migration logic)
- static/hyperscript/toggles._hs (toggle logic)
- tests/mjs/24-pdf-download-params.test.mjs (test expectations)
- tests/mjs/test-preference-migration.test.mjs (NEW)
- tests/mjs/verify-migration.test.mjs (NEW)

**PDFs Renamed:**
- cv-extended-with_skills-jamr-2025-en.pdf → cv-long-with_skills-jamr-2025-en.pdf
- cv-extended-with_skills-jamr-2025-es.pdf → cv-long-with_skills-jamr-2025-es.pdf

**Migration:** Automatic cookie migration from 'extended' → 'long' for seamless UX

## New Feature: Compact Sidebar Fonts

Reduces page count for short CV with skills from 6 → 5 pages:

**Implementation:**
- Location: internal/pdf/generator.go (lines 154-215)
- Cookie detection: `cookies["cv-length"] == "short"`
- Font reduction: 2-6% (0.94-0.98em) - very subtle
- Only activates for: `length=short` + `version=with_skills`
- Long version: Always uses full-size fonts

**Impact:**
- Page count: 6 pages → 5 pages (16.7% reduction)
- Readability: Maintained - fonts remain professional
- Design philosophy: Subtle, natural content flow

**Testing:**
- New test: TestPDFGenerator_CompactSidebarFonts
- Comprehensive coverage of cookie detection and PDF generation
- Manual verification: 5-page PDF with compact but readable fonts

**Documentation:**
- doc/LONG-PDF-GENERATION.md (NEW, 13 KB)
  - Complete feature documentation
  - Implementation details with code examples
  - Font size breakdown table
  - Testing and troubleshooting guides
  - Compact sidebar fonts section (comprehensive)

**Files Changed:**
- 11 modified (backend + frontend + docs)

juanatsap 1837a9b0ae quick fix to prod 2025-11-19 17:27:39 +00:00
juanatsap 43414b79ac fix: Override inline icon sizes to 1.2em across all sections
Problem: Inline icons embedded in responsibilities, courses, and
projects had explicit width='60' height='60' attributes that made
them too large (60px instead of ~16px).

Solution:
- Added CSS with !important to override inline width/height attributes
- Targeted inline icons in:
  * Course responsibilities and descriptions
  * Project descriptions and technologies
  * Experience responsibilities (within divs)
- Preserved large icons (80px) for main company/course/project logos

Changes:
- static/css/03-components/_courses.css: Override to 1.2em
- static/css/03-components/_projects.css: Override to 1.2em
- static/css/03-components/_cv-section.css: Override to 1.2em

Test Results:
 7 course inline icons: 16px × 16px
 Main company icons: 80px × 80px (preserved)

juanatsap 35a802cbd5 fix: Keep sidebar background consistent across themes
Change sidebar background from var(--sidebar-bg) to fixed #d1d4d2
so it remains the same light gray color in both light and dark themes.

The sidebar should provide a consistent visual anchor regardless
of the main content theme.

- Footer

**Key Features:**
- Structural fidelity: Skeletons mirror exact HTML structure of actual content
- Each section has realistic placeholders (e.g., 3 experience items, 2 projects)
- Smooth CSS transitions with shimmer animations
- Zero layout shift
- Component-level architecture allows independent loading states

**Technical Implementation:**
- Modified all section templates in templates/partials/sections/
- Added .component-wrapper with .actual-content + .skeleton-content structure
- Extended skeleton.css with structural skeleton classes
- JavaScript event handlers in main.js already handle all sections via CSS cascade

**Testing:**
- Manual Playwright test: 13/13 component wrappers verified
- Automated test: 7/7 tests passing
- All skeleton loaders show during language switches
- No stuck loading states

**Documentation:**
- Updated tests/TEST-SUMMARY.md with all 13 sections
- Updated doc/2-MODERN-WEB-TECHNIQUES.md with comprehensive details
- Added structural fidelity table showing skeleton elements for each section

Files modified: 14 templates + CSS + 2 docs

juanatsap 8c0328357b fix: remove CSPNonce from Matomo script (not implemented in backend)
ISSUE: Matomo analytics not loading in production

ROOT CAUSE:
- Matomo script had nonce="{{.CSPNonce}}" attribute
- Go backend doesn't generate CSPNonce template variable
- Empty nonce attribute caused CSP to block the script in production

FIX:
- Removed nonce attribute from Matomo script tag
- CSP header already includes 'unsafe-inline' so nonces not needed
- Script now loads correctly in both localhost and production

VERIFICATION:
- Matomo will now load and track pageviews in production
- Check browser console for _paq object
- Verify tracking in Matomo dashboard

juanatsap 481003fcf8 refactor: update skeleton header to pixel-perfect match actual layout
Updates skeleton header to exactly match the actual CV header layout with
photo absolutely positioned on the right side.

**Layout Changes:**
- Photo: 150x200px positioned absolutely (top: 15px, right: 15px)
- Name: 40px height (h1 size)
- Subtitle: 24px height (larger)
- Intro text: 90px height (3-4 lines)
- Header has padding-right: 185px to accommodate photo
- Removed flex layout, using absolute positioning like actual

**Visual Improvements:**
- Photo border: 3px solid #e8e8e8 (matches actual white border)
- No border-radius on photo (matches actual)
- Larger text blocks for better visual match
- Proper spacing between elements

**Tests:**
- test-skeleton-verify.mjs:  All 4 language switches pass
- Skeleton displays correctly on every transition

juanatsap e90e7f0a15 feat: implement skeleton loaders for language transitions
Implements component-level skeleton loaders that display during language
transitions, providing visual feedback while content swaps.

**Implementation:**
- Dual-state structure: each component has actual-content + skeleton-content
- CSS toggles visibility via opacity transitions (250ms)
- Global hyperscript listener on <body> for language button clicks
- Adds .loading class to parent containers that persist across OOB swaps
- Skeleton shapes mimic actual components (header, name, photo, intro)

**Key Technical Solutions:**
- Event delegation using event.target.matches('.selector-btn')
- Parent container targeting to survive HTMX OOB innerHTML swaps
- CSS descendant selector .loading .component-wrapper for triggering
- Shimmer animation with GPU acceleration (1.8s infinite)

**Files Modified:**
- static/css/skeleton.css: Complete skeleton system with shimmer animation
- templates/index.html: Global hyperscript for .loading class management
- templates/partials/sections/header.html: Dual-state component structure
- templates/partials/navigation/language-selector.html: Removed local hyperscript

**Tests:**
- test-skeleton-verify.mjs: Validates skeleton across 4 language switches
- All tests passing:  Consistent activation on every language change

juanatsap 534e0f16e5 feat: implement component-level skeleton loaders for language transitions
Implemented dual-state skeleton system as specified in prompt:
- Each component has actual-content + skeleton-content structure
- CSS toggles visibility via .loading class on component-wrapper
- Individual skeleton boxes (name, photo, intro, etc.) with shimmer animation
- Hyperscript triggers loading state during language switch

Changes:
- skeleton.css: Complete component-level skeleton CSS system with shimmer
- language-selector.html: Hyperscript to add/remove .loading class
- header.html: Dual-state structure with skeleton placeholders

Behavior:
- Click language button → .loading class added to components
- Actual content fades out (opacity → 0) in 250ms
- Skeleton boxes appear and shimmer
- After HTMX swap + 100ms delay → .loading class removed
- New content fades in (opacity → 1) in 250ms

Test Results:
 Component wrapper structure verified
 Dual-state toggle working correctly
 Skeleton elements present and animated
 Shimmer animation active (1.8s infinite loop)
 Accessibility: respects prefers-reduced-motion
 Print: skeletons hidden, content always visible

Next: Add skeleton structure to remaining components (experience, education, skills, projects)
2025-11-18 11:32:12 +00:00
juanatsap 7ea2e93fe1 fix: apply skeleton shimmer to content wrappers during language transitions
Previously, the .htmx-swapping class was only applied to the language
selector button target, not to the actual CV content containers that
were being swapped via hx-swap-oob.

Solution:
- Added hyperscript event handlers to language selector buttons
- On htmx:beforeRequest → add .htmx-swapping to both content wrappers
- On htmx:afterSwap → remove .htmx-swapping from both wrappers

Effect:
- Skeleton shimmer (opacity 0.3 + animated ::before overlay) now
  appears on CV content during language switch (~500ms duration)
- Smooth transition with shimmer effect inside content area
- No external overlay layer - effect is within existing DOM structure

Verified with Playwright test showing:
 .htmx-swapping class applied during swap
 Opacity changes to 0.3
 ::before pseudo-element with shimmer animation active
2025-11-18 08:47:21 +00:00
juanatsap c1f2f89555 feat: add skeleton shimmer effect during language transitions
Implements smooth skeleton loader animations during language switching:
- Uses HTMX's built-in .htmx-swapping class (no hyperscript needed)
- Content fades to 30% opacity during swap
- Shimmer animation overlays content during transition
- Respects prefers-reduced-motion accessibility setting
- Total transition: 500ms (250ms fade-out + 250ms fade-in)

Implementation approach:
- Simple CSS-only solution using ::before pseudo-element
- No overlay div - skeleton appears INSIDE content wrappers
- Works automatically with HTMX swap timing already configured
- GPU-accelerated shimmer animation (background-position)

Files changed:
- static/css/skeleton.css (NEW) - Shimmer animation styles
- templates/index.html - Added skeleton.css reference

juanatsap 52e97f1411 fix: exclude footer from zoom by moving it outside zoom-wrapper
The footer was being zoomed along with CV content because it was
inside the #zoom-wrapper div. This fix moves the footer outside the
zoom-wrapper so it remains at normal size regardless of zoom level.

Changes:
- Move footer template outside zoom-wrapper in index.html
- Add UI exclusion test (11-zoom-ui-exclusion.test.mjs)

Test coverage:
- Verify footer, action bar, and menu are outside zoom-wrapper (DOM)
- Verify UI elements remain unchanged when zooming to 200%
- Verify CV content properly zooms while UI stays fixed

Before: Footer inside zoom-wrapper (zoomed with content)
After: Footer outside zoom-wrapper (stays normal size)

juanatsap de67c73048 feat: increase zoom range from 175% to 300%
User can now zoom up to 300% for better readability.

Changes:
- Update zoom slider max from 175 to 300
- Update aria-valuemax to 300
- Update display label to show 300
- Update README to reflect new range (25%-300%)

Tested with curl - verified max="300" in HTML output
2025-11-17 17:03:17 +00:00
juanatsap 35a836adf3 fix: restore zoom level persistence on page load
Zoom level persistence was broken because hyperscript was setting the
container's value instead of the slider's value on page load.

Changes:
- Fix zoom-control.html line 10: set #zoom-slider's value (not 'my value')
- Add comprehensive zoom persistence test (10-zoom-persistence.test.mjs)
- Update cv-functions.js documentation to clarify hyperscript interop
- Add zoom control feature to README

Test results: 5/5 tests pass
- Zoom saves to localStorage when changed 
- Zoom restores correctly on page reload 
- Reset to 100% works and persists 

Architecture note:
- Hyperscript 'call' within _="" attributes requires global JS scope
- JavaScript wrappers bridge window exposure to hyperscript evaluate()
- Pattern: window.fn() → _hyperscript.evaluate('hyperscriptFn()')

juanatsap d2330f5d48 refactor: migrate toggle and hover sync functions from JavaScript to Hyperscript
BREAKING: Removed JavaScript toggle functions in favor of organized Hyperscript architecture

Changes:
- Created organized Hyperscript file structure (no def limit with latest version):
  • static/hyperscript/utils._hs (utility functions)
  • static/hyperscript/toggles._hs (CV length, icons, theme toggles)
  • static/hyperscript/hover-sync._hs (PDF/Print hover sync + zoom highlight)

- Removed functions._hs (renamed to utils._hs for better organization)

- Emptied static/js/cv-functions.js (kept file with migration notice)
  • toggleCVLength, toggleIcons, toggleTheme → toggles._hs
  • syncPdfHover, syncPrintHover, highlightZoomControl → hover-sync._hs

- Updated templates/index.html to load all 3 new hyperscript files

- Updated tests/mjs/1-toggles.test.mjs for responsive design
  • Added viewport detection for desktop vs mobile toggles
  • Tests now adapt to screen size

Rationale:
- Test 9 confirmed NO def limit with latest hyperscript (tested up to 5 defs)
- Better separation of concerns with category-based file organization
- Aligns with server-side hypermedia pattern (HTMX + Hyperscript)
- Eliminates workaround JavaScript duplication
- 9 total def statements across 3 files (proving no limit)

Verified:
 All hyperscript files load successfully (HTTP 200)
 Hyperscript library loads without errors
 Functions work correctly in browser
 No console errors
 Test 9 (def limit) passes with 5 def statements

juanatsap 0edcf8c221 fix: correct button order and restore smooth transitions
Fixes:
1.  Reversed button order - Info at bottom, Download at top
   - Desktop (bottom→top): Info → Shortcuts → Zoom → Print → Download
   - Mobile (left→right): Download → Print → Shortcuts → Info

2.  Restored smooth morphing transitions
   - Added transition: all 0.4s cubic-bezier(0.4, 0, 0.2, 1)
   - Container smoothly transforms from vertical to horizontal
   - Buttons smoothly reposition during responsive transition

3.  Preserved all special hover behaviors
   - Zoom button: Blue hover + highlights zoom control
   - Print button: White bg + green icon on hover (synchronized)
   - Download button: Red bg on hover (synchronized)
   - All sync functions working: syncPdfHover, syncPrintHover, highlightZoomControl

The flexbox container now has the correct button order AND smooth animations!
2025-11-16 14:26:49 +00:00
juanatsap 8eea5a660a feat: implement flexbox container for fixed buttons
Major architectural improvement for button management:

Desktop Layout (left side, vertical):
- Created .fixed-buttons-container positioned left: 2rem, bottom: 2rem
- Buttons stack vertically with flex-direction: column
- Order (bottom to top): Info → Shortcuts → Zoom → Print → Download
- 1rem (16px) gap between buttons
- All buttons 50×50px with consistent styling
- Easy to add/remove buttons - just add template to container

Mobile Layout (bottom center, horizontal):
- Container switches to flex-direction: row at @media (max-width: 900px)
- Centered with left: 50% and transform: translateX(-50%)
- 10px gap between buttons
- Zoom button hidden on mobile (display: none)
- 4 visible buttons: Info, Shortcuts, Print, Download

Benefits:
 Single source of truth - container manages all buttons
 Easy to add/remove buttons - no manual position calculations
 Responsive - automatic reflow from vertical to horizontal
 Maintainable - changes in one place affect all buttons
 Consistent spacing - gap property ensures even distribution
 Future-proof - adding button = adding template to container

Technical Implementation:
- Container uses position: fixed with flexbox
- Buttons use position: relative inside container (not fixed individually)
- All positioning managed by flexbox (gap, flex-direction, align-items)
- Hover states preserved with color-coded backgrounds per button
- Back-to-top button remains separate (not in container)

This replaces individual fixed positioning with a scalable flex layout.

This commit includes two major improvements:

1. Hyperscript Code Organization:
   - Extracted all hyperscript blocks >3 lines into reusable functions
   - Created 6 new functions in functions._hs:
     * toggleCVLength(isLong) - CV length toggle sync
     * toggleIcons(showIcons) - Icons toggle sync
     * toggleTheme(isClean) - Theme toggle sync
     * syncPdfHover(show) - PDF button synchronized hover
     * syncPrintHover(show) - Print button synchronized hover
     * highlightZoomControl(show) - Zoom control highlight effect
   - Reduced inline hyperscript from 11+ lines to 1-2 lines per element
   - Updated 8 template files to use function calls:
     * hamburger-menu.html
     * view-controls.html
     * action-buttons.html
     * download-button.html
     * print-friendly-button.html
     * zoom-toggle-button.html

2. Mobile Button Layout (max-width: 900px):
   - Repositioned three fixed buttons (PDF, Print, Info) horizontally at bottom center
   - Print button perfectly centered in viewport
   - Download button on left, Info button on right
   - Hidden zoom and shortcuts buttons on mobile (available in hamburger menu)
   - Removed conflicting old mobile styles that were hiding print button
   - Smooth hover transitions maintained with proper transform calculations

Technical details:
- Used CSS transform with calc() for precise horizontal positioning
- Maintained hover effects with combined translateX/translateY transforms
- Ensured accessibility with proper ARIA labels and spacing
- All functions check element existence before manipulation
- LocalStorage sync maintained across desktop/mobile toggles

juanatsap b9e9e09d71 feat: enhance zoom and print button UX
Print Button Improvements:
- Hover shows white background with green icon (was green bg + white icon)
- Applied to all print buttons: fixed, action bar, and menu
- Default state remains dark gray with white icon

Zoom Control Improvements:
- Text now 100% white (was 70-95% opacity) for better readability
- Increased font sizes: labels 0.95rem (was 0.8rem), current value 1.05rem (was 0.9rem)
- Hover zoom toggle button highlights zoom control with blue glow shadow
- Active zoom button uses semi-transparent blue rgba(52, 152, 219, 0.5) instead of solid

Z-Index Fix:
- Hamburger menu now appears above fixed buttons (z-index: 1000 vs 999)
