/* pipe — the marketing pages' whole stylesheet.
 *
 * Structure is basho.dev's system (base, shell, home, responsive), ported.
 * The SHEET is the pipeOS handout's: paper, ink, serif prose, one blue
 * accent — Sam's ruling 2026-08-26, resolving docs/mobile.md rule 2 against
 * the gold retune (#858/#860): the site converges on the artifact a buyer
 * holds. It is a second SYSTEM, not a skin — the pages that load it do not
 * load site.css (xtask's head_for picks exactly one sheet per page), so
 * nothing here has to out-rank anything, and nothing here can reach the app.
 *
 * Tokens keep basho's NAMES so the two files stay diffable; the VALUES are
 * the handout's, and every derived tint is a color-mix() on a token — no
 * colour literal lives outside :root (mobile.md rule 2 as amended).
 *
 * Component index — the canonical set:
 *   .nav            the header: brand + the accent "get started" left, links right
 *   .hero           the page-opening statement, sans, the breathing ring
 *   .info           one selling beat: label left, body right (basho's /rules)
 *   .panel / .stat  a raised card; .wgrid is the four-up of them
 *   .tiers / .tier  pricing: .stat cards with a bottom-pinned button
 *   pre.term        anything literally terminal; .p is the prompt
 *   .faq            details/summary, hairline rows
 *   .actions        a row of .button
 *   .docs           the docs shell: sidebar + measure, on the .info grid
 *   .home           the landing: the stage + the side panel
 *   footer .crawl   the sponsor crawl, then the legal line
 * A new marketing element is one of these or it argues its way in here.
