/*
 * ============================================================
 * site.css — every page of subtank.dev
 * ============================================================
 * WHY THIS EXISTS   2026-09-24. One stylesheet, cached once, for seven static
 *                   pages. Redesigned the same day the first release shipped:
 *                   the first site read as a demo — three grids of identical
 *                   glass cards and pill chips over the headline, the look a
 *                   generated landing page has. This one is an instrument,
 *                   like the app: sections open on a calibrated rule with a
 *                   numbered label in the margin (a fuel gauge's scale, not a
 *                   pill), and each section has a form of its own — the real
 *                   menu bar at real size, an annotated row, a spec table,
 *                   typeset rules, a pull quote, one download band.
 * WHAT IT DOES      Declares the three typefaces from /fonts (served by this
 *                   host; OFL notice in /fonts/OFL.txt), the colour tokens
 *                   (dark first, a light set swapped in by the system), and
 *                   every component the pages and site-release.mjs's
 *                   generated blocks use. Motion is CSS only: the stage
 *                   settles on load, sections rise as they scroll in where
 *                   the browser has scroll-driven animations, and all of it
 *                   stops for prefers-reduced-motion.
 * WHAT IT CANNOT DO Load anything from another host. Every page carries a CSP
 *                   of default-src 'none' with style, font and image from
 *                   'self' only — no script, and no inline style attribute
 *                   either, so bar widths in the illustrations are classes
 *                   (.w34). Content never waits on an animation to be seen.
 * ============================================================
