Part 1: Shared Utilities
- Create internal/fileutil package with FindDataFile() and LoadJSON()
- Create internal/lang package with language constants and validation
- Eliminate 46 lines of code duplication between cv/loader.go and ui/loader.go
- Simplify cv/loader.go from 69 to 36 lines (-48%)
- Simplify ui/loader.go from 56 to 24 lines (-57%)
Part 2: Validation Layer
- Add comprehensive validation in internal/models/cv/validation.go
- Validate Personal (name, email format, URLs)
- Validate Experience (required fields, dates)
- Validate Education (required fields)
- Validate Skills (proficiency ranges 1-5, categories)
- Validate Languages (proficiency levels 1-5)
- Validate Projects (title, URLs)
- Validate Meta (version, language)
- Integrate validation into LoadCV() - automatic on load
- Create ValidationError and ValidationErrors types for clear error reporting
- Report all validation errors at once (better UX)
Testing:

- Add tests for lang package (IsValid, Validate, All)
- Add 280+ validation test cases covering edge cases
- All tests pass with real CV data (cv-en.json, cv-es.json)
- Fixed validation to allow both URLs and local paths for gitRepoUrl
Documentation:
- Create _go-learning/refactorings/002-shared-utilities-validation.md
- Document architecture, benefits, testing, and interview talking points
- Explain WHY decisions were made (DRY, type safety, data integrity)
Benefits:
- DRY: Single source of truth for utilities
- Type safety: Language constants instead of magic strings
- Data integrity: Validation catches errors at load time
- Better errors: Clear messages showing all issues at once
- Maintainability: Centralized utilities easier to update
- Add findDataFile() helper to search up directory tree for data files
- Fixes tests running from subdirectories (internal/handlers)
- Install Chrome in GitHub Actions for PDF generation tests
This resolves test failures that have existed since PDF tests were introduced:
- Error: 'open data/cv-es.json: no such file or directory'
- Error: 'chrome failed to start'
Tests now properly locate data files from any working directory and
have Chrome available for PDF generation in CI environment.
**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 ✓
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

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

Technical changes:
- Add Action field to Reference model with omitempty JSON tag
- Implement conditional rendering for downloadPDF action in template

- Created separate ui-en.json and ui-es.json files for UI strings
- Removed 'ui' section from cv-en.json and cv-es.json
- Added LoadUI() function to load UI translations separately
- Updated handlers to load UI data independently from CV data
- Updated template to use .UI instead of .CV.UI
This separation follows proper concerns:
- CV JSON files contain only professional CV content
- UI JSON files contain only application interface strings
- Each can be updated independently without affecting the other
- Added 'ui' section to cv-en.json and cv-es.json with modal translations
- Updated Go models to include UI, InfoModal, and TechStack structs

When a project has a gitRepoUrl, the system automatically fetches the first
commit date from the repository. For current projects, it displays
"Present" (English) or "Presente" (Spanish) dynamically from the backend.
The La Porra project now uses git repository path for date calculation
instead of hardcoded JSON values.
