Add three new feature modules (reactions, bookmarks, polls) with corresponding database tables, indexes, and router registrations. Introduce `SESSION_MAX_AGE_REMEMBER` config for extended session duration, add `get_unread_messages` template global, and include operational defaults for rate limiting and session settings in `site_settings`.
Introduce a new `/leaderboard` endpoint ranking top 50 members by total stars, wire it into the app router and documentation. Implement `_backfill_gamification()` in `database.py` to compute XP/levels for existing accounts from prior posts, comments, votes, and follows. Extract `is_owner()`, `create_content_item()`, and `detail_context()` into `content.py` to centralize content creation, reward awarding, mention notifications, and attachment linking. Update comment creation/deletion in `comments.py` to use `award_rewards()` with `XP_COMMENT` and the new `is_owner()` helper. Add shared template partials documentation for vote bars, star buttons, post headers, and topic selectors to `AGENTS.md`.
Replace static form-based vote buttons with a new VoteManager class that submits votes via fetch, returns JSON with net/up/down/current value, and updates vote count spans using data-vote-count attributes across all templates. Add JSONResponse endpoint in votes router for AJAX requests, switch VoteManager import from Http to Toast for error feedback, and refactor link_attachments to handle comma-separated UIDs.
- Add .dockerignore, Dockerfile, and docker compose targets to Makefile for containerized deployment
- Implement gists router with CRUD operations, database schema, and polymorphic comment/vote reuse
- Create attachment upload system with thumbnail generation, MIME detection, and storage path management
- Add attachments_prune CLI command to clean orphaned attachment records and files
- Introduce rate limiting middleware with 60 requests per minute window
- Add custom 404 and 500 error handlers with SEO-optimized template responses
- Extend database initialization with gists and attachments indexes plus upload site settings defaults
- Update load_comments to include attachment mapping for comment resources
- Register gists and uploads routers in main application and update AGENTS.md documentation
Introduce `load_comments` helper supporting polymorphic target types (post, project, bug) with nested parent-child threading. Refactor comment creation to use `target_type`/`target_uid` and `resolve_target_redirect` for correct redirects. Replace raw UID-based post/project routes with slug-aware resolution via `resolve_post`/`resolve_project` and `make_combined_slug`. Update SEO, sitemap, and FAB styling to use slugs and hardcoded red accent. Add reusable `_comment_section.html` template.
