- Extract comment templates into reusable partials (_comment.html,
  _comment_form.html, _comment_list.html, _reply_form.html, etc.)
- Add HTMX progressive enhancement: inline form submission with
  partial responses, delta polling for live updates, form reset on
  success, success/moderation toast feedback
- Integrate Cloudflare Turnstile for invisible bot protection:
  server-side token validation with hostname check, fail-closed on
  errors/timeouts, feature-flagged via TURNSTILE_SECRET_KEY env var
- Auto-approve comments that pass Turnstile; keep manual approval
  as fallback when Turnstile is disabled (model default stays False)
- Add CommentReaction model with UniqueConstraint for session-based
  anonymous reactions (heart/thumbs-up), toggle support, separate
  rate-limit bucket (20/min)
- Add comment poll endpoint (GET /comments/poll/<id>/?after_id=N)
  for HTMX delta polling without duplicates
- Update CSP middleware to allow challenges.cloudflare.com in
  script-src, connect-src, and frame-src
- Self-host htmx.min.js (v2.0.4) to minimize CSP surface area
- Add django-htmx middleware and requests to dependencies
- Add Unapprove bulk action to Wagtail admin for moderation
- Extend PII purge command to anonymize reaction session_key
- Design refresh: neon glow avatars, solid hover shadows, gradient
  section header, cyan reply borders, grid-pattern empty state,
  neon-pink focus glow on form inputs
- Add turnstile_site_key to template context via context processor
- 18 new tests covering HTMX contracts, Turnstile success/failure/
  timeout/hostname-mismatch, polling deltas, reaction toggle/dedup/
  rate-limit, CSP headers, and PII purge extension

Closes #43
