/* Fulmaire brand: the one place the palette, type and base controls live.
 *
 * Every page links this file before its own <style>. A page may style its own
 * components, but it never redefines a token here: four pages each carrying a
 * copy of the palette is how the paper drifted to three shades of cream and
 * the ink to two blues. BRAND.md explains the choices; a test holds the rule.
 *
 * The identity is an Admiralty chart, not wildlife (NAMING.md): chart paper,
 * fine ink linework, and magenta for what a paddler has claimed, which is the
 * chart's own colour for lights and marks.
