"""
Audio-lipsync card renderer — vertical PIL card scoped to the
``docs/automations/LTX-2.3/audio-lipsync/`` iteration loop.

Sibling to ``scripts/make_card.py`` (base-1step). Shares palette,
font fallback chain, and section primitives so the two families read
as a set, but the data sources are deliberately narrower:

Two — and only two — source families feed this card:

  1. The five ``Text Multiline`` nodes tracked by the loop config
     (name / relay_overrides / overlay - info / overlay - feedback /
     working_folder).
  2. The active ``LTXDirector`` node's own widget values and
     input-socket wiring (Koolook for modified runs, upstream original
     for A/B comparison; epsilon, frame_rate, timeline_data segments +
     audioSegments, use_custom_audio toggle, audio_vae link state).

Notably absent: BasicScheduler / KSamplerSelect / RandomNoise /
CFGGuider widget scrapes, ``_dev_build.json`` fork-state, ``git status``
output. Those don't define what this loop sweeps. Adding them would
push the card into showing values the maintainer's curated multiline
notes don't claim to summarise.

Card sections (top to bottom):

  HEADER            run-NNN — {name} · date · job · workflow filename
  KNOB STATE        relay_overrides (the per-render knob)
  BASE / RUN        source workflow · copied-from workflow · working folder
  DIRECTOR READINGS Director · pin tag · epsilon · Audio src
  SEGMENTS          segment list with time ranges + coverage rows
  POST-RENDER       feedback body + outcome scores

Two entry points:

1. From loop_audio.py at end-of-snapshot:

       from scripts.make_card_audio import render_audio_card
       render_audio_card(state, run_dir / "card.png")

2. Standalone, against an existing run folder (re-render after a
   layout tweak):

       python scripts/make_card_audio.py <run_dir>
