/*
 * The stylesheet for every page the server renders: the landing page at /, the
 * share page at /s/{shareId}, and the Terms and Privacy pages.
 *
 * A bedtime app should look like the sky it is read under, so every page is a
 * pastel day-sky blue in light mode and a soft night blue, with stars, in dark
 * mode. Coral stays the brand colour (shared/ui/theme/Theme.kt) and sunny doubles
 * as moonlight. `--coral-ink` is coral for *text*: the brand coral is too light to
 * read on pale blue and too loud on navy, so each theme gets its own shade.
 *
 * No fonts are fetched — a system stack renders instantly and cannot be the
 * reason the page is slow. The landing page asks for the rounded system face
 * where one exists (Apple platforms) and falls back to the ordinary one.
