LOW 1 (notes XSS): device.notes textarea content now goes through
esc(). Notes weren't in the sanitizeBody allow-list at write time, so
HTML in the field would render unescaped on the device-detail page.
LOW 2 (CSP): enabled Helmet contentSecurityPolicy with default-src
'self', script-src 'self', style-src 'self' 'unsafe-inline', plus the
data:/blob:/https: image and media sources the player needs. Strict
script-src blocks <script> injection; script-src-attr 'unsafe-inline'
keeps existing inline onclick handlers working until they can be
refactored to addEventListener (TODO comment in code).
CSP applies to /app and most other paths. Skipped on the public
widget and kiosk render endpoints, the landing page, and /player —
those legitimately need inline scripts/styles. upgrade-insecure-
requests is explicitly disabled so HTTP-only self-hosted LAN
deployments aren't broken.
Refactored two inline onclick handlers in index.html to data-close-
modal attributes wired by a delegated listener in app.js. Was the
only blocker for /app under strict script-src.
LOW 3 (CORS): Express CORS now only allows screentinker.com (and
subdomains) + localhost in production. SELF_HOSTED=true bypasses the
allowlist (operator owns their deployment). Development mode stays
open. Same policy applied to the Socket.IO CORS config which was
previously origin: '*'. Native clients (Android, server-to-server,
kiosk iframes) send no Origin and pass through unchanged.

New content_folders table with hierarchical parent_id and per-user
scoping. content.folder_id added (ON DELETE SET NULL so deleting a
folder drops items back to root). New /api/folders route exposes
list/create/rename/move/delete with cycle detection on move.
Content library UI: breadcrumb navigation, subfolder grid, "+ New
Folder" creates inside the current folder, drag-and-drop content
items onto folder cards to move them, and the edit modal has a
folder dropdown showing each folder's full path.
Per-user scoping is enforced server-side: every folder query
filters by user_id, and folder ownership is checked on both folder
mutations and content.folder_id updates.

Extend the public /api/content/:id/file gate to unlock content referenced
by widgets (previously only playlists unlocked it), so device browsers
and kiosk iframes can fetch logos and background images that widgets
embed.
Security: scope the widget lookup to the content owner's widgets only
(w.user_id = content.user_id). Otherwise a user could unlock another
user's content file by creating their own widget whose config references
the victim's content UUID. The pre-existing playlist gate has the same
shape and is left for a separate fix.
Also adds a 30/min rate limit on POST /api/widgets/preview, which
inlines user content as base64 and is memory-intensive.
Perf note: the widgets.config LIKE scan is O(n). Fine at current scale;
revisit with a content_widget_refs join table if the widget table grows.

Player polls /api/version every 30s and reloads if the hash changes.
Server hash now includes player/index.html and sw.js so player code
updates are detected without requiring a hard refresh.

- Push playlist updates to devices instantly via WebSocket on all
assignment mutations (add, update, delete, reorder, copy)
