/* THE FIRST SCREEN — what index.html shows before the showroom's JavaScript has run, and what the showroom's
   own loader (ui/Loader) keeps showing, in the same places, until the room is ready: the logotype, what the
   page is, a loading bar and the links to the site's pages. It is also the whole page for a reader that never
   runs the room — a crawler, a browser without WebGL — so it is real text, not a picture of it.

   A file and not a <style> in the page: the CSP refuses inline styles (public/_headers). Published as
   assets/boot-<hash>.css by site/plugin.ts, so a changed sheet is a new address and no cache can pair an old one
   with a new page. Small on purpose, and asked for straight after the HTML, before the bundle. */

/* Inter from the first frame (the same files and subsets as src/styles.css, which repeats these for the
   showroom): without them the first screen is set in the system's face and changes font the moment the
   bundle's stylesheet arrives. The Latin file is preloaded by the page's head (site/layout.ts). */
