lint and check only ever audit a composition against its own rules, so a
scene that renders nothing like the artifact it reproduces still passes
both. compare --against adds the outward-looking gate: per-time SSIM (via
ffmpeg's ssim filter), ink bounding-box deltas, a reference-over-replica
contact sheet, a red/cyan deviation overlay, and --fail-under to exit
non-zero on a measured floor.
Skills now route reference-bearing briefs to it, and the entry skill says
to read only the routed workflow's SKILL.md.
