/**
 * @fileoverview Layout and components of the Phase3 proposal, written against semantic roles
 * (`--bg`, `--fg`, `--accent-text`...) so that every visual direction is a set of role values in
 * directions.css plus a few flourishes, never a second stylesheet.
 *
 * @remarks
 * Roles map only to the brand tokens in tokens.css (inventory A4, A5): no colour or font outside the
 * live site's own palette. The defaults here are the "editorial" direction, which is the live site's
 * own language (huge Instrument Sans, grey ground, underlined links, one carbon block) finished.
 * Contrast of every text role was checked against its ground (S2, 02/11/2026); the violet used for
 * text is `--l1-ink`, because `--l1` on the grey ground is below 4.5:1.
