   RIGHT ANGLE STUDIO — design tokens (v2, gallery-light)
   Replicates the spirit of rightangle.studio: a clean, light
   gallery wall where the photographs carry the colour. Palette:
   Paper (gallery white), Ink (text), Silver (captions), and the
   brand red #BC332B from the RK logo for rules and accents.
   Type: Archivo expanded (display) · Spectral (editorial)
   · IBM Plex Mono (EXIF / utility).
   Signature: the 90° viewfinder bracket on every photograph.
