/* Deckboy's site, in Deckboy's clothes.
 *
 * The palette is not a taste decision. Sampling a capture of the application
 * running its DEFAULT theme returns, in order of area:
 *
 *   #fcfe1f  bright yellow   the buttons and the lit chrome
 *   #1f601f  dark green      the panels everything sits on
 *   #f3fdca  pale cream      secondary ink
 *   #94ae79  sage            muted ink and rules
 *
 * So the site uses those. An earlier version of this file used the Game Boy
 * DMG greens, because the screenshot that had been to hand was shot in the
 * "gameboy" colourway -- one of about thirty themes the app ships -- and I
 * took a theme for the identity. The default is yellow on green.
 *
 * Long body copy is set in the cream rather than the yellow. The application
 * can put #fcfe1f on #1f601f because its text is short and its panels are
 * small; a paragraph of it on a web page is a migraine. Headings, buttons and
 * the lit accents keep the yellow, which is where the app uses it too.
 *
 * The font is not a choice either. The application draws its branding in
 * Press Start 2P by name (native/core/paths.cpp: "retro pixel font used for
 * the Deckboy branding/logo") and its interface in a monospace. Headings are
 * Press Start 2P; everything else is mono.
 *
 * Press Start 2P is used ONLY at headline sizes -- it is enormously wide and
 * has no lower-case rhythm, so body copy set in it is unreadable, and a site
 * nobody can read is not on brand, it is broken.
 */

/* The application's OWN font files, copied from data/. Not Google's cut of
 * Press Start 2P but the very binary the deck draws its wordmark with, and
 * Liberation Mono because that is what the interface sets its text in. Served
 * from the site so the page does not depend on a third party to look like
 * itself. */
