Original-release bitmap subs (PGS, VobSub, dvd_subtitle) are first-class,
not stop-gaps. They're the canonical studio render — bitmap encoding is
just a format choice, not a quality compromise. OCR'd or AI-rebuilt
sidecars introduce transcription error that the source doesn't have.
STYLE.md changes:
- New "Source priority" section with 4 tiers: original text > original
bitmap > trusted text rips > WhisperX rebuild.
- "What lands on disk" loosened: at least one English stream (embedded
OR sidecar), keep embedded codec as-is, sidecar still .srt.
- New "OCR bitmap -> text" section documenting pgsrip recipe as an
optional UX-nicety augmentation, not a correctness fix.
- "Why these rules" now explains why original > pretty (esp. for older
shows like Futurama S1-3 / early Archer where the master is the only
authoritative source and upscale artifacts already dominate).
STOPGAP-SUBS.md: header note clarifying bitmap-from-disc is NOT a
stop-gap; lists Lilo & Stitch (2002) and Archer (2009) S02 as examples
of correct-as-shipped library entries.
