Home Radio Live — hourly bucket swap on rolling playlist

OVERRIDES runtime profile: uses Spotify Web API directly, does not invoke the claude CLI.

Hourly at HH:01 SAST. Rebuilds the contents of the single public Spotify playlist "Home Radio - Live" (owned by econ, made public so HEOS conrelma can play it without playlist-modify scope) with the tracks from whichever day-part bucket is active right now.

Bucket selection (SAST hour → bucket): | 00–05 | late | | 05–11 | morning | | 11–14 | midday | | 14–18 | afternoon | | 18–22 | evening | | 22–24 | night |

Day group = weekday/sat/sun by current SAST date.

Spotify Connect tolerates content swaps mid-playback: the currently-playing track finishes, the rebuilt lookahead queue takes over within ~30s. Speaker keeps playing through bucket boundaries without a stop/restart, like a real radio station rotation.

Operator log entries written under live.<day_group>.<day_part> for visibility into freshness across rebuilds.

Phase 3 of the Home Radio project. The HA automation home_radio_live_morning_kick (in /config/automations.yaml) starts playback of "Home Radio - Live" on Kitchen Heos every morning; from there the hourly content swap handles the rest.

Playback guard: hourly refresh may update playlist contents at any hour, but it must not auto-replay Kitchen/House during quiet hours (21:00-04:59 SAST) or while HA input_boolean.presence is off. This prevents the scheduler from restarting music after the 20:00/no-presence night-off automation intentionally stopped it.
