/*
 * Buccaneer's Horizon website: one style sheet for the landing page, the legal pages and the 404
 * page. Colours come from the game's palette (BuccaneersHorizon/core/.../ui/Palette.kt), fonts are
 * the game's own (Sancreek for titles, Fira Sans for text), self-hosted under the SIL OFL as WOFF
 * (the TTF tables zlib-compressed, font data unchanged; see Server/web/README.md). Every browser takes
 * the WOFF; the TTF after it is only a fallback that is never downloaded when WOFF is supported.
 * Rules (Server/legal/README.md): no @import, url() only to files under /assets/.
 * Contrast: every text colour pair below is >= 4.5:1 (WCAG AA) in both colour schemes.
