A small always-on-top mpv window renders the local time in a screen
corner. Implementation notes:
- Transparent lavfi canvas (color=...@0.0, --alpha=yes) so the camera
video shows through; no new dependencies. If the compositor can't do
alpha it degrades to a dark backing, still legible.
- Time drawn as an ASS osd-overlay pushed over mpv IPC once a second:
white fill + black outline (\bord), so it reads on both bright (day)
and dark (night) scenes without sampling the picture. Formatting the
text in Go avoids any filtergraph escaping.
- Time computed with time.LoadLocation against a configured IANA zone
(default "Local"), so it's correct regardless of the host clock's zone
and handles DST. A bad zone name fails at startup.
- Managed on the daemon's own context (survives layout switches); the
daemon keeps it positioned and raised above camera tiles. ensureClock
is a no-op when the clock config + resolution are unchanged, so a
reload never disturbs it.
Config: new `clock` section (enabled, timezone, format, corner,
font_size, width, height, margin) with defaults and corner validation.
Documented in README and config.example (shipped enabled, America/Denver,
24-hour w/ seconds). Tests cover corner geometry.

Over hours the wall drifted ~15s behind real-time: the Pi decodes a hair
slower than real-time, and since RTSP-over-TCP delivers every byte, that
small deficit buffers up instead of being dropped — and a live stream
can't be seeked back to the live edge.
Add player.resync_seconds (0 = off): the daemon reconnects each stream to
the live edge on that interval via mpv loadfile-replace over IPC, cycling
one tile at a time so only a single tile ever blips. Reusing the running
mpv process means no window teardown. At 600s this caps drift to a couple
seconds. config.example.yaml ships it at 600; README documents the knob
and the "also lighten decode load" caveat.

- Skip stream restarts when a reload resolves to the identical wall
(same URLs, tile geometry, player settings) — saving an unrelated
config edit no longer blanks the screen.
- Replace per-tile placement polling (a swaymsg fork per tile per second,
plus 150ms get_tree polling per tile at startup) with one shared loop:
a single get_tree snapshot per tick, re-placing only drifted windows,
relaxing to a 2s tick once settled.
- Mute streams by default (--no-audio) to skip an audio decoder per
stream; opt back in with player.audio: true.
- Graceful, parallel mpv teardown via cmd.Cancel/WaitDelay, fixing the
double-Wait race between Stop and Supervise and cutting worst-case
layout switches from ~2s x N streams to ~2s total.
- status: probe mpv IPC outside the daemon mutex so a slow probe can't
block layout switches.
- View sync: reuse the Protect session across ticks (re-login only on
expiry) and pick up view_refresh_seconds changes without a restart.
- Health strikes keyed by player, not slot, so they never carry across
layout switches; prune stale entries.
- New `rtsp-streamer reload` CLI; fix dead sort in `layout ls`; back off
on persistent control-socket accept errors; fsync config before the
atomic rename (SD-card power-cut safety); bump IPC client deadline;
gofmt stragglers.

views ls/dump/import copy a Protect live view (cameras + grid) into a
layout; grid inferred from slot count (asymmetric presets TBD, see
views dump). Imported layouts link back via protect_view.
Daemon re-syncs the active linked view every view_refresh_seconds (0=
off), so Protect-side edits appear on the wall. Needs the controller
password at runtime; off by default keeps the wall credential-free.
Shared viewmap package used by CLI and daemon.

Cameras carry multiple stream URLs (streams: high/medium/low); each
tile picks one via Quality (auto/high/low). Small tiles can pull the
low substream to cut Pi decode load. discover --enable-rtsp takes a
comma list (high,low), enables each channel, records all enabled ones.
TUI: q cycles a tile quality (shown in the tile); discover enables
high+low. Player: --framedrop + low-delay demuxer flags; player.max_fps.
