YUNUS EMRE VURGUN — "DETAIL" LAYER
===============================================================================
Loaded last of the six core sheets (variables, ui-rebuild, ebook, jelly, blueprint, detail).
The jelly skin owns the palette, type, mascot and spring; the blueprint layer turned its
decoration into a drafting sheet. This layer adds the finish the blueprint pass left out, with
the same parts and nothing new in colour or type:

  · keys are machined: an engraved dish line inside the rim, a lit chamfer over a navy skirt,
    real travel when pressed; the red one keeps its jelly gloss on a deeper red skirt
  · toggles latch (a pressed navy key), counts and timestamps read as instrument labels
  · photos and thumbnails sit on a mat; avatars sit in a dial bezel with a red index
  · the end of an article is a set of plates (share keys, the book, further reading, the author)
    instead of loose text links

Every rule consumes tokens from variables.css (plus the two paper tints blueprint.css already
names); motion is transform/opacity only and stops under prefers-reduced-motion.
