/*
 * The marketing page's stylesheet.
 *
 * Separate from `style.css` on purpose, and not importing it. The editor's
 * sheet is ninety kilobytes describing panels, gizmos and popovers, none of
 * which exists here; loading it would be the largest single cost on the page
 * whose whole job is to be quick.
 *
 * ## The palette is not in here
 *
 * It is in `apps/web/palette.css`, which every page of the site links before
 * its own sheet. Three files carried a hand-copied palette until update 81 made
 * this one dark and the other two stayed light-or-dark, so a person went from a
 * dark first page to a white sign-in form. The layout below is still this
 * page's alone — that is the thing that must not be shared, and the reason
 * `login.css` and `legal.css` still exist.
 *
 * ## Why one theme
 *
 * Following the reader is right for a page of prose and wrong for one whose
 * layout *is* six product screenshots: a page that renders in two themes needs
 * its pictures taken in two themes, and nobody was ever going to maintain both
 * sets. `tools/landing-shot.mjs` opens the editor with `colorScheme: 'dark'` so
 * the pictures are of the same product this page is.
