/* ============================================================
   Cutting Straight — "Text & Apparatus" design tokens
   ------------------------------------------------------------
   Canonical source of truth for the visual system.
   Captured verbatim 2026-07-19 from the approved mockups:
     · study page — artifact b42a3e09-55e0-4fa4-983f-aa42fc8c5a45
     · home page  — artifact 42285c12-0e30-4a5f-b856-c599077a4949
   Both carried an identical token block; this file is that block.

   The idea: the Word is set in warm serif; ALL apparatus and
   chrome is mono. Colour is semantic, never decorative —
   indigo = the plumb line (grounding/authority), pine = settled,
   ochre = open/honest, brick = load-bearing warning, brass = the
   single controlled metallic accent.

   Four declaration blocks are required, in this order:
     1. :root                        — light defaults
     2. @media (prefers-color-scheme: dark)
     3. :root[data-theme="light"]    — explicit toggle
     4. :root[data-theme="dark"]     — explicit toggle
   Blocks 3 & 4 must beat the media query in BOTH directions,
   or the theme toggle breaks for users whose OS disagrees.
