/**
 * DEKS Unified Design System — Peregrine GeoServices palette, light register.
 *
 * THE ONE TOKEN SOURCE. Every DEKS page links this file from
 * /shared/static/css/deks.css, which both the container and each module mount
 * (deks_ui.mount_shared_static). Nine modules used to paste a copy of the token
 * block into their own <style>; those copies are gone. Change a value here and
 * it changes everywhere — that is the entire point.
 *
 * PALETTE: Peregrine GeoServices brand kit
 * (Peregrine_GeoServices_Brand_Kit.pptx), transcribed verbatim below. The
 * company brand is the platform's brand. Source of truth and the derived
 * light-band values: peregrine-geoservices-site/docs/style-decision.md.
 *
 *   Basalt        #191C1D   authority, depth        -> ink
 *   Survey White  #F3F1EA   clarity, space         -> the page ground
 *   Mineral Blue  #1769A8   information, direction -> interactive primary
 *   Field Green   #58A85D   growth, environment    -> success / live data
 *   Signal Ochre  #E7A640   attention, signal      -> the scarce accent
 *   Iron Grey     #777B78   structure, support     -> rules, quiet labels
 *
 * TWO DELIBERATE DEPARTURES FROM THE KIT, both recorded in
 * docs/specs/design-system-unification.md:
 *
 * 1. The kit's page is DARK (Basalt ground). DEKS is light — the owner retired
 *    light-text-on-dark on 2026-09-16 — so this applies the kit's own light
 *    band, which it defines for long-form reading, as the whole register.
 * 2. The kit makes Signal Ochre the button colour, "nothing else, deliberately".
 *    That holds for a page with two CTAs. An app has hundreds of buttons, and
 *    in DEKS amber already means *attention* and marks the FID gate — so
 *    Mineral Blue is the interactive primary and ochre stays scarce.
 *
 * CONTRAST IS MEASURED, NOT ASSUMED. Every value used for text below carries
 * its WCAG ratio against Survey White. The kit's own warning holds: raw Signal
 * Ochre (1.87:1) and raw Iron Grey (3.80:1) are NOT body text — use the text
 * variants.
 *
 * Not yet applied from the kit, because each is a change of shape rather than
 * colour: radius 2px ("effectively square"), the Archivo display face, and the
 * IBM Plex Mono annotation layer. Tracked in the spec.
