/* pipe — the docs pages' whole stylesheet.
 *
 * This is pipeOS's system (the box dashboard at pipe.local:
 * overlay/usr/local/share/pipeos/web/static/style.css), ported: warm paper
 * with a dark variant the OS picks, system-ui for reading, monospace only
 * where the content IS terminal, a left panel of rounded nav rows that
 * becomes a bottom tab bar on a phone. A third SYSTEM beside site.css and
 * mkt.css, not a skin — a docs page loads this sheet and no other (xtask's
 * head_for picks exactly one per page), so nothing here has to out-rank
 * anything and nothing here can reach the app or the marketing pages.
 *
 * Tokens keep pipeOS's names and shapes on purpose: the two files stay
 * diffable, and a fix found on one side carries to the other. The palette
 * is the one deliberate departure — cool greys where the box wears warm
 * paper, and robin's-egg blue where it wears green — a whiter, bluer egg. It is
 * spent super light as the FILL (the active pill, the mark's ring, the
 * get-started chip); text set in the accent takes the deep end of the same
 * hue, because a pastel cannot carry a letterform and still clear WCAG AA.
 *
 * Component index — the canonical set:
 *   nav[data-nav]   the site's side panel: brand + icon rows (chrome.ts
 *                   refills it); hidden on a phone, where the .tabbar takes
 *                   over (the pipeOS move — thumbs live at the bottom)
 *   .tabbar         the phone's fixed bottom bar, built by chrome.ts
 *   .docs-wrap      the docs shell: section rail + measure
 *   .docs-nav       the section rail: icon rows, accent pill on the current
 *                   page; a horizontal pill row on a phone
 *   .docs-body      the prose: h1/h2, tables, table.q command tables
 *   pre.term        anything literally terminal; stays DARK in both themes,
 *                   because it quotes the terminal rather than being the page
 *   footer          the one-liner legal line
 * A new docs element is one of these or it argues its way in here.
