/* ==========================================================================
   Wandernote — App workspace
   A candlelit study: leather-toned sidebar rail, parchment editor with a
   whisper of paper grain, lantern-glow hovers, wax-seal markers, hairline
   rules. Texture at low volume; typography does the heavy lifting.

   Consumes css/tokens.css only — no parallel colour/spacing values. Deeper
   "leather" and inset tones are DERIVED from tokens via color-mix so both
   themes stay in family. Motion is gated on --motion-ok (reduced-motion sets
   it to 0 in tokens.css) and every transition names its properties.
