Newsletter nudge — was calling /api/study-account/profile (wrong endpoint, ignored subscription). Now correctly calls /api/study-account/preferences with PATCH.
Security:
Email regex — replaced the permissive [^\s@]+@[^\s@]+ pattern with a proper RFC-compliant regex in contact.js and downloads.js
Avatar magic bytes — server now checks actual PNG/JPEG/GIF/WEBP header bytes, not just the data URL prefix
Certificate rate limit — public /api/public/certificate/:token now has a 30 req/15min limiter
Session absolute TTL — admin sessions now have a 30-day hard cap; a stolen token can no longer be kept alive indefinitely by passive reads
Account lockout — 5 failed logins locks a study account for 1 hour
CSP headers — Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy headers added globally
Data integrity:
Cascade delete — deleting a study account now also removes their certificates, community posts, comments, and progress file
UX / reliability:
Escape key on modals — all 3 modal groups (study index, notes, account) now close on Escape
Display name min-length — empty spaces-only names rejected; if provided, must be ≥2 chars
Note save rate limit — 30 saves/minute per user max
Analytics fetch timeout — 5s AbortController so a hanging server doesn't block the browser indefinitely
Email validation on signup — frontend catches bad email formats before hitting the server
Cleanup:
Deduplicated download forms — StudyDownloadForm and ResourceDownloadForm now share a single DownloadForm base; both are now thin wrappers
Tracks scroll depth (25/50/75/90%), time on page, UTM parameters, outbound
link clicks, search queries, audio pause/completion/listen time, and 404s.
Logged-in study users are now tied to their visitor record and surfaced in
the admin recent visits table. Scroll position resets on every route change.

The .section-resources CSS overrides were breaking the Downloads page
resource link layout. Added .section-external-sites class to the
ExternalSitesSection and scoped all image/layout overrides to it.

Adds the configured imageUrl as a full-width banner at the top of each

- **Tag filter bar** appears above the grid whenever any download has tags assigned. Chips for "All" + each unique tag, centered under the heading.
- **Clicking a tag** filters the grid to only matching downloads. Clicking the active tag again (or "All") clears the filter.
- **Empty state** — if a tag has no results it shows a friendly message instead of a blank grid.
- The filter only shows when tags exist — so it's invisible today (your 3 current downloads have no tags) and appears automatically once you start tagging items in the admin.
To use it: go to Admin → Downloads → edit a download item → add tags like `Colossians`, `Worksheet`, `Devotional`. Those tags will show up as filter chips on the public page instantly after publishing.
