+# Cache Package
+
+## Overview
+
+The `cache` package provides application-level caching for CV and UI data, eliminating per-request file I/O by loading all data once at application startup. This improves performance and reduces latency for all handler operations.
+
+**Key Benefits:**
+- Single load at startup, fast reads during request handling
+- Thread-safe concurrent access using `sync.RWMutex`
+- Language-keyed access ("en", "es")
+- Fast-fail strategy: fails at startup if any language data cannot be loaded
+
+## Architecture
+
+### DataCache Structure
+
+```go
+type DataCache struct {
+ cv map[string]*cvmodel.CV // CV data indexed by language
+ ui map[string]*uimodel.UI // UI data indexed by language
+ mu sync.RWMutex // Protects concurrent reads
+}
+```
+
+The cache stores pointer references to CV and UI models, loaded from YAML files. Since reads are frequent and writes never occur, `sync.RWMutex` provides efficient concurrent access.
+
+## Usage
+
+### Initialization
+
+The cache is created once at application startup in `main.go`:
+
+```go
+// Initialize data cache (load CV and UI data once at startup)
+dataCache, err := cache.New([]string{"en", "es"})
+if err != nil {
+ log.Fatalf("Failed to initialize data cache: %v", err)
+}
+```
+
+This loads CV and UI data for English and Spanish. If any language fails to load, the entire startup fails—catch errors early rather than on first request.
+
+### Handler Integration
+
+The cache is injected into handlers via constructor:
+
+```go
+cvHandler := handlers.NewCVHandler(templateMgr, serverAddr, emailService, dataCache)
+```
+
+Handlers access cached data using language-specific getters:
+
+```go
+func (h *CVHandler) renderPage(w http.ResponseWriter, r *http.Request) {
+ lang := r.URL.Query().Get("lang")
+ cv := h.dataCache.GetCV(lang)
+ ui := h.dataCache.GetUI(lang)
+
+ // Use cv and ui data for rendering...
+}
+```
+
+## API Reference
+
+### `New(languages []string) (*DataCache, error)`
+
+Creates and initializes a new cache with data for the specified languages.
+
+**Parameters:**
+- `languages`: List of language codes to load (e.g., `[]string{"en", "es"}`)
+
+**Returns:**
+- `*DataCache`: Initialized cache instance
+- `error`: Non-nil if any language fails to load
+
+**Behavior:**
+- Returns `nil` and error if any language's CV or UI data fails to load
+- Empty language list creates empty cache (no error)
+- Fails at startup rather than deferring errors to request time
+
+**Example:**
+```go
+cache, err := cache.New([]string{"en", "es"})
+if err != nil {
+ log.Fatalf("Failed to initialize cache: %v", err)
+}
+```
+
+### `GetCV(lang string) *cvmodel.CV`
+
+Retrieves cached CV data for the specified language.
+
+**Parameters:**
+- `lang`: Language code (e.g., "en", "es")
+
+**Returns:**
+- `*cvmodel.CV`: Pointer to CV data, or `nil` if language not found
+- **Note:** Callers must check for `nil` before dereferencing
+
+**Thread Safety:** Safe for concurrent reads
+
+**Example:**
+```go
+cv := cache.GetCV("en")
+if cv == nil {
+ // Handle missing language
+ return fmt.Errorf("CV not available for language: en")
+}
+// Use cv...
+```
+
+### `GetUI(lang string) *uimodel.UI`
+
+Retrieves cached UI data for the specified language.
+
+**Parameters:**
+- `lang`: Language code (e.g., "en", "es")
+
+**Returns:**
+- `*uimodel.UI`: Pointer to UI data, or `nil` if language not found
+
+**Thread Safety:** Safe for concurrent reads
+
+**Example:**
+```go
+ui := cache.GetUI("es")
+if ui != nil {
+ title := ui.Navigation.Title
+}
+```
+
+### `Languages() []string`
+
+Returns all language codes currently cached.
+
+**Returns:**
+- `[]string`: Slice of available language codes (order not guaranteed)
+
+**Thread Safety:** Safe for concurrent reads
+
+**Example:**
+```go
+langs := cache.Languages()
+for _, lang := range langs {
+ cv := cache.GetCV(lang)
+ // Process CV for each language...
+}
+```
+
+## Mutating Cached Data
+
+### Important: Deep Copies for Mutable Fields
+
+Since cache stores pointer references, handlers that modify CV slices must create deep copies before modification:
+
+```go
+// In handlers that modify experience/projects:
+func prepareTemplateData(cv *cvmodel.CV) *cvmodel.CV {
+ // Create copies of mutable slices
+ copy := &cvmodel.CV{
+ Personal: cv.Personal,
+ Experience: append([]cvmodel.Experience{}, cv.Experience...), // Deep copy
+ Projects: append([]cvmodel.Project{}, cv.Projects...), // Deep copy
+ Education: cv.Education,
+ Skills: cv.Skills,
+ }
+
+ // Now safe to modify copy.Experience and copy.Projects
+ for i := range copy.Experience {
+ copy.Experience[i].YearsOfExperience = calculateYears()
+ }
+
+ return copy
+}
+```
+
+This prevents handlers from accidentally mutating cached data during request processing.
+
+## Supported Languages
+
+Currently configured for:
+- `"en"` - English
+- `"es"` - Spanish
+
+To add a new language, update `main.go`:
+
+```go
+dataCache, err := cache.New([]string{"en", "es", "fr"}) // Add "fr"
+```
+
+Ensure YAML data files exist in the data directory for the new language, or startup will fail.
+
+## Error Handling
+
+### Startup Failures
+
+The fast-fail strategy ensures all data issues are caught before the server starts:
+
+```go
+dataCache, err := cache.New([]string{"en", "es"})
+if err != nil {
+ // Example error messages:
+ // "load CV for 'fr': file not found"
+ // "load UI for 'es': invalid YAML"
+ log.Fatalf("Failed to initialize data cache: %v", err)
+}
+```
+
+### Runtime Handling
+
+Handlers should gracefully handle missing languages:
+
+```go
+cv := cache.GetCV(lang)
+if cv == nil {
+ http.Error(w, "Language not supported", http.StatusNotFound)
+ return
+}
+```
+
+## Performance Considerations
+
+### I/O Efficiency
+- **Single Load:** CV and UI YAML files are parsed once at startup
+- **No Per-Request I/O:** Handler requests never touch disk
+- **Memory Trade-off:** Stores decoded objects in memory
+
+### Concurrency
+- **RWMutex:** Optimized for high read throughput, zero writes
+- **No Contention:** 100+ concurrent reads verified in tests
+- **Nil Returns:** Fast path for missing languages (map lookup only)
+
+### Memory Usage
+- Minimal overhead: Two maps + one mutex
+- Proportional to number of languages loaded
+- Shared object references (no duplication per request)
+
+## Testing
+
+Run the comprehensive test suite:
+
+```bash
+go test ./internal/cache -v
+```
+
+Test coverage includes:
+- Cache initialization with valid/invalid languages
+- CV and UI data retrieval
+- Thread safety with concurrent reads
+- Data integrity verification
+- Empty language list handling
+
+## Dependencies
+
+- `internal/models/cv` - CV data model
+- `internal/models/ui` - UI data model
+- Go standard library: `sync`

+
+Create a complete CSS sprite system for company, project, and course icons using Go.
+This dramatically improves page load performance by reducing HTTP requests from 44+ individual images to just 3 sprite sheets.
+
+PERFORMANCE IMPACT:
+- Current: 23 company + 12 project + 9 course = 44 separate HTTP requests
+- Target: 3 sprite images (one per category)
+- Result: ~93% reduction in image requests
+
+CRITICAL REQUIREMENTS:
+1. **Automated normalization**: Users throw ANY size image into source folders → system automatically normalizes to icon size
+2. **Go implementation**: Use Go with native/standard libraries (prefer stdlib, avoid heavy dependencies)
+3. **One command**: `make sprites` handles everything (normalize + generate + update registry)
+4. **Documentation required**: Create doc/XX-SPRITES.md following existing doc/ patterns
+5. **Tests required**: Create tests/mjs/XX-sprites.test.mjs following existing test patterns
+
+
+
+Project: CV website (Go + HTMX)
+
+Current image structure:
+- static/images/companies/*.png (23 images, various sizes)
+- static/images/projects/*.png (12 images, various sizes)
+- static/images/courses/*.png (9 images, various sizes)
+
+JSON references (data/cv-en.json, data/cv-es.json):
+- experience[].companyLogo: "filename.png"
+- projects[].projectLogo: "filename.png"
+- courses[].courseLogo: "filename.png"
+
+Existing patterns to follow:
+- Tests: tests/mjs/XX-name.test.mjs (Playwright E2E, numbered)
+- Docs: doc/XX-NAME.md (numbered markdown)
+- Scripts: scripts/*.sh (deployment tools)
+- Makefile: existing targets for build, test, css-prod
+
+
+
+Before implementing, thoroughly research:
+1. Go native image processing libraries (image/png, image/draw, golang.org/x/image)
+2. Best approach for image resizing with aspect ratio preservation in Go
+3. How to composite images into horizontal strips in Go
+4. Whether to use cmd/sprites/ pattern or internal/tools/ for Go tooling
+
+
+
+## 1. Go Sprite Generator Tool
+
+Create a Go tool that:
+- Scans source folders for images (any size/format)
+- Normalizes each to 48x48px (1x) and 96x96px (2x retina)
+- Maintains aspect ratio, centers on transparent background
+- Combines into horizontal sprite strips
+- Generates ICON-REGISTRY.md with positions
+
+Location options to evaluate:
+- `cmd/sprites/main.go` (separate binary)
+- `internal/tools/sprites/` (internal package)
+- Prefer native Go libs: `image`, `image/png`, `image/draw`
+- If needed: `golang.org/x/image/draw` for better scaling
+
+## 2. Icon Size Standards
+
+- Base: 48x48px (readable at 100% zoom, works up to 300%)
+- Retina: 96x96px (@2x for high-DPI displays)
+- WHY 48px: Standard icon size, crisp at all zoom levels, small file size
+
+## 3. Naming Convention
+
+Source images (user drops these - ANY size):
+```
+static/images/companies/olympic-broadcasting.png (could be 500x300)
+static/images/companies/sap.png (could be 100x100)
+```
+
+Generated outputs:
+```
+static/images/sprites/sprite-companies.png (horizontal strip, 48px tall)
+static/images/sprites/sprite-companies@2x.png (horizontal strip, 96px tall)
+static/images/sprites/sprite-projects.png
+static/images/sprites/sprite-projects@2x.png
+static/images/sprites/sprite-courses.png
+static/images/sprites/sprite-courses@2x.png
+```
+
+## 4. JSON Integration
+
+Add `logoIndex` to each entry in cv-en.json and cv-es.json:
+```json
+{
+ "company": "Olympic Broadcasting Services",
+ "companyLogo": "olympic-broadcasting.png",
+ "logoIndex": 0
+}
+```
+
+**⚠️ DO NOT TOUCH - Preserve these existing patterns:**
+
+1. **Empty logo fields** - Some projects have `"projectLogo": ""` (no image). Leave as-is, no logoIndex.
+ ```json
+ // KEEP AS-IS - no sprite integration
+ { "projectLogo": "", ... }
+ ```
+
+2. **Iconify icons in HTML** - Course/project items use inline `` for individual entries (e.g., Go courses from Udemy). These are in the `responsibilities` array, NOT the logo field. Do not modify.
+ ```json
+ // KEEP AS-IS - uses Iconify system, not image sprites
+ "responsibilities": [
+ "Go - The Complete Guide
"
+ ]
+ ```
+
+**RULE: Only add logoIndex when there's an actual PNG file in companyLogo/projectLogo/courseLogo**
+
+**INDEX ORDERING: Chronological (oldest first)**
+- Index 0 = oldest/first experience in career
+- Last index = most recent/current experience
+- This matches natural reading order (career progression)
+
+**KEEP CV JSON CLEAN:**
+- Only add `logoIndex` field - nothing else
+- NO offset in JSON (calculated as `index × 48px` in CSS)
+- The CV JSON is an INFO document, minimize pollution
+
+The Go tool generates a SEPARATE mapping file (not in CV JSON):
+```json
+// static/images/sprites/sprite-map.json (reference only, not used at runtime)
+{
+ "companies": [
+ {"index": 0, "name": "oldest-company.png"},
+ {"index": 1, "name": "next-company.png"},
+ {"index": 10, "name": "olympic-broadcasting.png"}
+ ],
+ "projects": [...],
+ "courses": [...]
+}
+```
+This file is for documentation/debugging only - the CSS calculates offset from index.
+
+## 5. CSS Integration
+
+Create `static/css/04-interactive/_sprites.css`:
+```css
+.icon-sprite {
+ display: inline-block;
+ width: 48px;
+ height: 48px;
+ background-repeat: no-repeat;
+ background-size: auto 48px;
+}
+
+.icon-company {
+ background-image: url('/static/images/sprites/sprite-companies.png');
+ background-position-x: calc(var(--icon-index, 0) * -48px);
+}
+
+/* Retina */
+@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
+ .icon-company {
+ background-image: url('/static/images/sprites/sprite-companies@2x.png');
+ background-size: auto 48px; /* Display at 1x size */
+ }
+}
+```
+
+## 6. Template Integration
+
+Update templates to use sprites:
+```html
+{{if ge .logoIndex 0}}
+
+{{else if .companyLogo}}
+
+{{end}}
+```
+
+
+
+PHASE 1: Go Tool Creation
+1. Research best Go approach for image processing
+2. Create sprite generator tool
+3. Implement: scan → normalize → combine → output
+4. Generate sprite-map.json for reference
+
+PHASE 2: Integration
+1. Create _sprites.css with positioning classes
+2. Update main.css to import sprites
+3. Update JSON files with logoIndex values
+4. Modify templates to render sprites
+
+PHASE 3: Makefile & Workflow
+1. Add `make sprites` target
+2. Add `make sprites-clean` target
+3. Document workflow in doc/XX-SPRITES.md
+
+PHASE 4: Testing & Documentation
+1. Create tests/mjs/XX-sprites.test.mjs
+2. Create doc/XX-SPRITES.md
+3. Update PROJECT-MEMORY.md with sprite system rules
+
+
+
+
+
+REQUIRED TESTS (must all pass):
+1. `make sprites` completes without errors
+2. Sprite images exist in static/images/sprites/
+3. sprite-map.json has correct positions for all icons
+4. `make build` passes
+5. `make css-prod` compiles successfully
+6. E2E test verifies:
+ - Only 3 sprite images loaded (not 44 individual)
+ - All logos display correctly
+ - Sprites work at different zoom levels
+ - Retina sprites load on high-DPI
+
+**SHOWCASE PAGE (Critical for visual verification):**
+Create `static/sprite-showcase.html` - A standalone HTML page that displays:
+- All 3 sprite sheets as full images (visible strips)
+- Grid of all individual icons extracted via CSS positioning
+- Icon index numbers displayed under each icon
+- Category headers (Companies, Projects, Courses)
+- Zoom test section (100%, 200%, 300%)
+- Retina vs 1x comparison
+
+This page serves as:
+1. Visual QA during development
+2. Documentation for icon positions
+3. Test fixture for E2E tests
+4. Reference for future icon additions
+
+Example structure:
+```html
+
+
+
+ Sprite Showcase
+
+
+
+ CSS Sprite Showcase
+
+
+ Companies (Full Sprite)
+ 
+
+ Individual Icons
+
+
+
+
+
+
+
+
Zoom Test
+ 100%:
+ 200%:
+ 300%:
+
+
+
+```
+
+The Go tool should AUTO-GENERATE this showcase page from sprite-map.json.
+
+Manual verification:
+```bash
+# Check sprite dimensions (should be width = 48 * icon_count, height = 48)
+identify static/images/sprites/sprite-companies.png
+
+# Open showcase page
+open http://localhost:1999/static/sprite-showcase.html
+
+# Verify network requests
+# Open browser DevTools → Network → filter Images
+# Should see: sprite-companies.png, sprite-projects.png, sprite-courses.png
+# Should NOT see: individual logo files
+```
+
+
+
