feat(templates): Add microformats2 h-feed and p-category markup for tags

Implement Phase 2 of v1.3.0 per microformats-tags-design.md

Template Updates:
- templates/index.html: Add h-feed properties (u-url, enhanced p-author with u-photo/p-note, feed-level u-photo)
- templates/index.html: Add p-category markup with rel="tag" to note previews
- templates/note.html: Add p-category markup with rel="tag" for tags
- templates/note.html: Enhance author h-card with u-photo and p-note (hidden for parsers)
- templates/note.html: Document u-photo placement outside e-content per draft spec
- templates/tag.html: Create new tag archive template with h-feed structure

Key Decisions Applied:
- Tags ordered alphabetically by display_name (ready for backend)
- rel="tag" on all p-category links per microformats2 spec
- Author bio (p-note) hidden with display: none for semantic parsing
- Dual u-photo elements intentional for parser compatibility
- Graceful fallback when author photo/bio not available

Templates are backward compatible and ready for backend integration.

+# v1.3.0 Phase 2: Templates Implementation Report
+
+**Date**: 2025-12-10
+**Developer**: StarPunk Developer Agent
+**Phase**: Phase 2 - Templates
+**Status**: Complete
+
+## Summary
+
+Successfully implemented Phase 2 of the v1.3.0 Microformats2 Compliance and Tags feature. All template updates have been completed according to the design specification in `microformats-tags-design.md`.
+
+## Changes Implemented
+
+### 1. Updated `templates/index.html`
+
+Added h-feed required properties per microformats2 specification:
+
+- **u-url**: Added self-referencing feed URL (hidden with `display: none`)
+- **Enhanced p-author h-card**:
+  - Added `u-photo` when author.photo is available
+  - Added `p-note` (bio) when author.note is available
+  - Maintained hidden state for semantic parsing
+- **Feed-level u-photo**: Added duplicate u-photo for broad parser compatibility (intentional per architect decision)
+- **p-category markup**: Added tag links with `rel="tag"` attribute on note previews
+  - Uses `tag.name` for URL (normalized)
+  - Displays `tag.display_name` (preserves case)
+
+### 2. Updated `templates/note.html`
+
+Enhanced individual note pages with:
+
+- **u-photo placement documentation**: Added comment explaining that u-photo must be direct child of h-entry (not inside e-content) per draft spec
+- **p-category markup**: Added tags section in footer with:
+  - `p-category` class on each tag link
+  - `rel="tag"` attribute per microformats2 specification
+  - Links to `/tag/<normalized_name>` route
+- **Enhanced author h-card**:
+  - Reordered: photo first, then name/url
+  - Added `p-note` (bio) with `display: none` for semantic-only parsing
+  - Graceful fallback when photo or bio not available
+
+### 3. Created `templates/tag.html`
+
+New template for tag archive pages:
+
+- Extends `base.html` and imports `display_media` macro
+- Uses h-feed structure with p-name showing tag display name
+- Shows all notes with the tag (no pagination for v1.3.0)
+- Reuses same note preview structure as index.html for consistency:
+  - Conditional p-name for explicit titles
+  - Media previews
+  - Truncated e-content (300 chars)
+  - Full note metadata including tags, timestamp, author
+- Empty state message when no notes found
+- Back navigation link to homepage
+
+## Key Design Decisions Applied
+
+All architect Q&A decisions were correctly implemented:
+
+1. **Tag ordering**: Alphabetically by display_name (case-insensitive) - ready for backend
+2. **rel="tag" attribute**: Added to all p-category links per specification
+3. **Author bio visibility**: Hidden with `display: none` - semantic only for parsers
+4. **Dual u-photo elements**: Maintained intentionally for parser compatibility
+5. **u-photo placement**: Verified and documented as correct (outside e-content)
+
+## Files Changed
+
+### Modified Files
+- `/home/phil/Projects/starpunk/templates/index.html`
+- `/home/phil/Projects/starpunk/templates/note.html`
+
+### New Files
+- `/home/phil/Projects/starpunk/templates/tag.html`
+
+## Verification
+
+### Template Structure Checks
+
+All templates follow the architect's microformats2 specifications:
+
+- h-feed on index and tag pages with required properties (p-name, u-url, p-author, u-photo)
+- h-entry on note previews and individual pages with required properties (e-content, dt-published, u-url)
+- p-category markup with rel="tag" on all tag links
+- Enhanced h-card with u-photo and p-note where available
+- Graceful fallback for missing author properties
+
+### Code Quality
+
+- Clean, readable Jinja2 syntax
+- Consistent with existing template patterns
+- Comprehensive comments explaining microformats decisions
+- No hardcoded values - all URLs use `url_for()`
+- Proper conditional rendering for optional fields
+
+## Dependencies for Next Phase
+
+Templates are ready and will work once backend implementation is complete:
+
+- **Phase 1 backend**: Must implement `tags` module and update `notes.py` to populate `note.tags`
+- **Phase 3 routes**: Tag links will 404 until `/tag/<tag>` route is implemented
+- **Context processor**: Author data already injected via existing context processor
+
+## Testing Notes
+
+Templates can be manually inspected but full testing requires:
+
+1. Backend implementation to populate `note.tags` property
+2. Tag route implementation for tag archive pages
+3. Author discovery system (already exists) providing photo and bio data
+
+## Standards Compliance
+
+All changes follow:
+
+- Microformats2 h-feed specification
+- Microformats2 h-entry specification
+- Microformats2 h-card specification
+- Microformats2 p-category specification with rel="tag"
+- Project coding standards for templates
+- Existing template patterns and structure
+
+## Issues Encountered
+
+None. All template updates completed successfully according to specification.
+
+## Next Steps
+
+Ready for Phase 3 implementation:
+1. Add tag archive route to `starpunk/routes/public.py`
+2. Update admin forms for tag editing
+3. Load tags in public routes (index, note)
+
+## Notes
+
+- The test failure in `test_migration_race_condition.py` is a pre-existing flaky test unrelated to template changes
+- Templates are backward compatible - work fine when `note.tags` is empty or None
+- No CSS changes required per architect decision (out of scope)
