/* ===================================================================
       SEMANTIC TOKENS
       One strategy for the whole page (Section 8.A, option 2): CSS variables,
       exposed to Tailwind in js/tw-config-home.js so `bg-surface` and
       `style="color:var(--body)"` resolve to the same value.

       The hues are the app's shipped brand tokens
       (apps/mobile/src/design/tokens.ts). What changed is their deployment:
       the previous build put every light section inside a luminance band of
       0.081, which is what read as monotony. The light family now spans
       0.815 to 0.959 and breaks hue once, on a sage-tinted band.
