/* Kinpath homepage.
 *
 * Loaded after policy.css, which owns the shared tokens, the font faces and the
 * policy-page furniture. Nothing here may change how the policy routes render —
 * every rule is scoped under .home or a home- prefix.
 *
 * Two principles, both from the brief:
 *
 *   1. The page is complete before any script runs. Every section carries its
 *      own background and its own contrast, so the palette passage from warm
 *      paper through evening plum to quiet dawn happens in CSS alone. The
 *      canvas deepens it; it does not deliver it. Delete the canvas and this
 *      page still reads as intended.
 *   2. Stillness is the register. Long measures, generous rests, one accent
 *      colour used sparingly, and no motion that asks to be watched.
