Wall editor: replaces the small grid with a Figma-style pan/zoom canvas. Each
display is a rectangle that can be dragged/resized to match its physical
arrangement; a separate semi-transparent player rect overlays the screens and
defines what content plays where. Drag empty space to pan, wheel to zoom,
"Center" button auto-fits content. Per-rect numeric x/y/w/h panel; arrow keys
nudge by 1px (10px with shift). Negative coordinates supported for screens
offset above/left of the origin. Coords rounded to integers on save.
Wall rendering: each device receives screen_rect + player_rect, maps the
player into its viewport with vw/vh and object-fit:fill so vertical position
of every source pixel is identical across devices that share viewport height.
Leader emits wall:sync at 4Hz with sent_at timestamp; followers apply
latency-adjusted target and use playbackRate ±3% for sub-300ms drift,
hard-seek for >300ms. Followers stay muted; leader unmutes via gesture with
AudioContext priming and pause+play retry to bypass Firefox autoplay.
"Tap to enable audio" overlay as a final fallback.
Reconnect handling: server re-evaluates leader on device:register so the
top-left tile reclaims leadership when it returns. Followers emit
wall:sync-request on entering wall mode (incl. reconnect) so they snap to
position immediately instead of drifting until the next periodic tick.
Group dissolve: removing a device from its last group clears its playlist
to mirror wall-leave semantics. Leaving a group with playlists on remaining
groups inherits the next group's playlist.
Dashboard: walls render as their own card section (hidden the device cards
they contain). Multi-select checkboxes on cards + "Create Video Wall" toolbar
action that creates the wall, removes devices from groups, and opens the
editor. dashboard:wall-changed broadcast triggers live re-render. Per-card
playback progress bar driven by play_start events forwarded from devices.
Security: PUT /walls/:id/devices verifies caller owns each device (or has
team-owner access via the widgets pattern), preventing cross-tenant device
takeover. wall:sync and wall:sync-request validate that the sending device
is a member of the named wall; relay re-stamps device_id with currentDeviceId
so clients can't spoof or shadow-exclude peers.
Schema: video_walls += player_x/y/width/height, playlist_id;
video_wall_devices += canvas_x/y/width/height. All idempotent migrations.

Landing page (frontend/landing.html):
- Title now includes "Self-Hosted" for that keyword
- Description appended "MIT licensed."
- Keywords aligned to spec (digital signage raspberry pi, digital
signage android tv, video wall software, kiosk software, etc.)
- SoftwareApplication JSON-LD: added applicationSubCategory
"DigitalSignage", license URL, refreshed description
- Image alt text + og:image:alt + twitter:image:alt now include
"open-source digital signage"
- New Resources section above the CTA with 6 cards linking to all
new guides and comparison pages
- Footer rewritten as a 5-column grid (Brand / Guides / Compare /
Project / Legal) with the new internal links
New SEO pages, all dark-themed, mobile-responsive, ASCII-only:
- frontend/css/seo-page.css (shared nav/footer/article/table styles)
- frontend/compare/yodeck-alternative.html
- frontend/compare/screencloud-alternative.html
- frontend/compare/optisigns-alternative.html
- frontend/guides/raspberry-pi-digital-signage.html
- frontend/guides/digital-signage-android-tv.html
- frontend/guides/self-hosted-digital-signage.html
Each new page has unique title/description/canonical, OG and Twitter
card tags, BreadcrumbList JSON-LD, single h1, proper h2/h3 nesting,
visible breadcrumb, comparison table or step-by-step ordered list,
"Related guides" cross-link block, and a CTA.
Sitemap (frontend/sitemap.xml): added all 6 new URLs with appropriate
priority (0.8 for compare pages, 0.9 for guides). Existing landing
(1.0) and legal pages preserved.
Robots (frontend/robots.txt): allow /compare/ and /guides/, disallow
/player (was previously allowed by mistake).
Server (server/server.js): added explicit GET /sitemap.xml and
GET /robots.txt routes ahead of the static middleware so the
Content-Type is guaranteed.

- Toast now announces via role="status"/aria-live="polite" by default,
and role="alert"/aria-live="assertive" for errors. Screen readers
previously got nothing when notifications appeared.
- Move playlist-item flex-wrap:wrap from inline style into the
@media (max-width: 768px) block so desktop rows don't wrap controls
when the viewport is intermediate-narrow.

- Wrap wide tables (admin, settings, reports) in .table-wrap with
min-width on the table so they scroll horizontally on narrow screens
instead of collapsing rows.
- Add global .table-wrap { overflow-x: auto } utility.
- Mobile: add mask-image fade on .tabs right edge to hint scrollability
when tabs overflow; flex-shrink:0 on .tab keeps labels intact.

- Buttons: min-height 44px (36px for .btn-sm, 40px for .btn-icon) on mobile
- Inputs/selects/textarea: font-size 16px (prevents iOS focus zoom), min-height 44px
- Pairing input: scaled letter-spacing down so 6 digits fit at 375px width
- Modals at 95vw: tighter header/body/footer padding so content breathes
- Toast container: bar-style full-width (left/right:12px) instead of
fixed-right 280px that clipped below 400px viewports
