/* ==========================================================================
   Noctuary — AEM Owl skin
   Product: a night desk (leaf + plate + verso/recto). Not a dashboard.

   Tokens
   ------
   Color: indigo-ink + copper lamp. Copper is reserved for the one CTA.
   Dark: surfaces lift by luminance. Primaries desaturated ~15%.
   Type: Fraunces (display) + Figtree (UI). Perfect fourth 1.333 from 16.
   Space: 8pt only — 8 / 16 / 24 / 32 / 48 / 64. Leaf rules sit on 32.
   Motion: named durations + easings. Reduced-motion collapses to instant.
   Icons: 24 grid, 1.5 stroke, square caps. See /skins/owl/icons/
