/*
 * Foldsmith — landing page.
 *
 * Metaphor: a forge. Cold navy steel, one hot-metal hue, hard edges softened only where a hand would
 * touch them. Type does the shouting, not colour: a single accent with an actual job (the thing you
 * can click, or the thing that changed), never decoration.
 *
 * Committed to one world — dark. No light variant, because a forge is not a bright room.
 * Zero external requests: no web fonts, no CDN, no analytics. The page has to hold itself to the
 * same standard the product claims.
