/* THE HELP CENTER (dist/help/), on the tokens ks-tokens.v1.css publishes and
 * the section, shell, button and type classes ks-home-v20.v1.css already
 * defines. Only what is new to a help page lives here: the search, the
 * audience tabs, the answer lists, and an article's reading column.
 *
 * Linked directly by every page tools/lib/help-center.mjs generates, so it is
 * registered in tests/repo/every-stylesheet-is-reachable.spec.ts.
 *
 * MOBILE FIRST: base rules are the phone; media queries widen. NO COLOUR IS
 * DEFINED HERE — every value is a token, so the page follows the platform
 * palette and its contrast clamps. No decorative boxes (the owner's direction
 * of 2026-09-25): structure comes from type, space and hairlines. */
