/*
 * DeckHQ, the site.
 *
 * One look: the product's own. The page is the dark studio the app's chrome is
 * drawn in, and the pictures are the lit floor on the table in the middle of
 * it. There is no light scheme here, because a second one would be the same
 * pictures on a ground they were never drawn for.
 *
 * NO WEB FONT. The two families below are named and never fetched: a machine
 * that has them shows them, every other machine shows its own system face,
 * and the fallback is the design. Nothing in this file loads anything.
 *
 * Colour: the neutrals, amber and crimson are the app's and the mark's. Amber
 * is the accent. Crimson means a session is waiting on you and is used for
 * nothing else; it is a fill and a dot and never sets a word. The state
 * colours appear once, in the key that explains them.
