   A film-lab / release-print aesthetic: near-black stock, a safety-leader
   red accent for primary actions, a densitometer teal for technical/HDR
   flags, and a stencil-condensed display face over a mono "spec readout"
   face for technical data. Signature motif: a sprocket-hole rail used as
   both a section divider and the quality-picker drag handle.
