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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
