/* shell.css — XBOT design system + site chrome.
 *
 * The single stylesheet for every frontend page. It owns:
 *   1. design tokens (colour, type, spacing, radii, elevation)
 *   2. base layout + typography
 *   3. the header/footer shell (.ms-*, injected by shell.js)
 *   4. shared components: buttons, cards, chips, badges, forms,
 *      pricing tiers, FAQ disclosures, prose, landing sections
 * Pages keep only a one-line <style> that sets --main-w (their
 * content width) plus anything genuinely unique to that page.
 *
 * Dark-first: the brand surface is the near-black + teal identity
 * of the bot avatar. A light scheme follows prefers-color-scheme.
 * No webfonts, no libraries — one cached request, system type.
