"""content.py — NIGHTWAVE station content banks (pure stdlib, Py3.9).

Single source of truth for the autonomous show. The SONG bank is served to the
browser (GET /api/songs) so the client renders the generative music + the
now-playing plate, and the server uses each song's title/artist for the
`song_intro` segment. The other banks feed the templated segment kinds
(station_id / weather / dedication) and the sonic logo.

Musical params on each song drive the in-browser generative engine:
  key    : root note name (the engine maps it to a MIDI root)
  scale  : major | minor | dorian | lydian | pentatonic_minor
  tempo  : BPM (60-90, late-night pace)
  timbre : rhodes | sine_pad | triangle_pluck | soft_saw | music_box
  vibe   : a human label (used in the DJ's intro flavor; not load-bearing)
