Subject: [PATCH] feat: Extend skeleton loaders to all 13 CV sections with
 structural fidelity

Implemented comprehensive skeleton loaders for the entire CV curriculum,
providing smooth loading animations during language transitions across
all sections.

**Sections Implemented (13 total):**
- Header (title-badges + personal info)
- Education
- Skills Summary
- Experience (with company logos, descriptions, responsibilities)
- Awards (with logos, issuers, descriptions)
- Projects (with icons, descriptions, tech stacks)
- Courses (with icons, institutions, dates)
- Languages
- References
- Other Information
- Skills Sidebars (left and right)
- 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

-**Key Innovation:** Component-level architecture allows each CV section to independently show loading state without affecting rest of page. Skeletons are absolutely positioned overlays, so they don't disrupt document flow.
+**Key Innovation:**
+- **Structural fidelity** - Each skeleton mirrors the exact HTML structure of its actual content (not just generic boxes)
+- **Component-level architecture** - Each CV section independently shows loading state without affecting rest of page
+- **Absolutely positioned overlays** - Skeletons don't disrupt document flow, preventing layout shift
+- **Realistic placeholders** - Multiple skeleton items per section (e.g., 3 experience items, 2 projects) match expected content count
