/* Shared design tokens and layout chrome (nav rail, mobile tab bar) for
   the Directory, ECA Detail, and Gallery pages. Ported from the Claude
   Design redesign handoff - see /docs (not shipped) for the original
   spec. Colors are authored in oklch() per the handoff for perceptual
   consistency; this app already targets modern Safari/Chrome (iPad/Mac),
   which both support oklch().

   One deliberate deviation from the handoff: group headers use a plain
   hyphen ("North - Floor 2") instead of an em dash, per house style. */
