/* The front page's own design system.
 *
 * Deliberately a second stylesheet rather than an edit to `styles.css`: that file is the one
 * `pricing.html` is built on, and this page's redesign changes tokens, type and component shapes
 * wholesale. Sharing one file would mean either breaking the price list or keeping two conflicting
 * sets of tokens in it. Two files, two pages, still no build step - the property this repository
 * actually cares about. Bringing `pricing.html` onto this system is its own piece of work.
 *
 * Dark-first: the bare `:root` block below is the dark palette, because the page was designed as a
 * control panel and reads as one. A light viewer gets the same design re-tokenised, never inverted.
