/*
 * The landing page's stylesheet (153).
 *
 * Hand-written, and not Tailwind — the one place in this repository where that is the simpler answer.
 * This is one static page with one copy of each component on it, and no second page it has to stay
 * consistent with; a build step, a scanned source list and a committed generated file would all exist to
 * produce what is written here directly. The console keeps Tailwind because it has fifteen templates that
 * do have to agree with each other (131).
 *
 * Every class is prefixed `pk-`, which is not decoration: every HTML file under `templates/` is scanned
 * as a Tailwind source for the console's build, so a class named `grid` or `card` in this file's markup
 * would silently add rules to the console's stylesheet. A prefixed name matches no Tailwind utility and
 * generates nothing.
 *
 * (That sentence originally spelled the glob out, which closed this comment on its own `*` `/` and threw
 * away the `:root` block below it. The page rendered in Times for exactly as long as it took to ask the
 * browser what `--pk-sans` had resolved to.)
 *
 * The palette is the console's ("harbour indigo"), by value rather than by import — the two surfaces share no code
 * (`ConsoleSecurity.md` §1), and a landing page that could not render without the console's asset
 * pipeline would be a landing page that disappears when the console is switched off. Both themes are
 * here for the same reason the console has both: the operating system already knows the answer.
 *
 * Motion is CSS alone — the page's policy allows no script. The hero enters once; the aurora drifts and
 * the marquee loops; sections rise into view on a scroll timeline where the browser has one, and simply
 * stand where they are where it does not. Every animation stops under `prefers-reduced-motion`.
