/* =========================================================
   SMIO × Hexaly — Platform app design system.
   Ported from the marketing site (smiochallenge.com) "FIELD"
   theme: paper background, ink typography, Hexaly orange accent,
   navy as architecture color. Routing as visual language.

   Two layers:
     1. Core system  — tokens + components shared with the
        marketing site (nav, hero, page-header, sections, cards,
        callouts, table.tbl, tags, buttons, formula, footer, prose).
     2. App layer     — adopts the platform's existing semantic
        classes (table.board, .warning/.success, .help, .pill,
        bks-*, .board-tabs, .subnav, .panel, etc.) onto the same
        tokens so runtime/JS hooks survive untouched.
