/* Nacient public site — site-owned token layer (Phase-3 group A).
 *
 * The marketing-site surface class's colour, status, and utility vocabulary,
 * materialising the values Decision: Marketing-Site Dark Scheme, Status and
 * Utility Token Tier, and the Mobile Text Floor (corpus 03cd1c3b) held
 * Decision-only for "the Phase-3 re-expressed site sheet, its named future
 * carrier" — plus the two corrective items its Consequences order for this
 * build: the critical swap (#b3261e/#f08b82 -> #963325/#e3978c) and the
 * private surface's flat --pv-crit re-pointed to the scheme-aware critical.
 *
 * Light values are the ratified light sheet's, ratified as seen. The dark set
 * is 03cd1c3b ruling 1's: values live once in the --_dk-* block and the two
 * dark selectors only remap, so the schemes cannot drift (the built
 * dual-selector mechanism — an explicit data-theme choice honoured first,
 * prefers-color-scheme as the fallback — carried as ratified).
 *
 * Reconciled against the brand-tokens artifact (tooling/brand-tokens/dist):
 * no name declared here is a name that artifact emits. Two built names were
 * renamed at this reconciliation: --link-ink -> --link and --elevation-1 ->
 * --shadow-1. The artifact owns both original names with diverging dark
 * resolutions (its --link-ink darkens to --primary-200; its --elevation-1
 * resolves to none under the surface-shift rule, which 03cd1c3b ruling 1
 * narrowly supersedes for this surface class only), so a shared name would
 * make theming load-order-dependent wherever both sheets load. Values and
 * rendered pixels are unchanged by the renames.
 *
 * The type/spacing token tier (hierarchy Decision 605a547a ruling 4) lands
 * at group E (the sixteen-role stratum at the end of this file): values are
 * the ratified-as-seen transcription (adoption snapshot DESIGN-SYSTEM.md
 * "The de-facto type scale (as built)") with exactly one movement — body
 * 17.5px -> 18px, the Founder's 2026-08-04 election (e6bf20fd annotation,
 * inside its locked 18-19px ruling-2 disclosure; measure stays ~64ch per
 * ruling 1). Every other role re-anchors value-preserving: where a role had
 * multiple built candidate values, the token carries the modal/primary value
 * and divergent seats keep their own clamp() beside it, so zero rendered
 * pixels move anywhere except the body step. The motion tier reconciled at
 * group D (GROUP-D-LOCATE_2026-08-04.md): the design source's
 * --motion-*, --ease-*, and --radius-* re-declarations are value-identical to the
 * artifact's owned names, so the re-expression consumes the artifact names by
 * reference and mints no site-class duplicate; the one site-class motion name
 * is --spring (end of file).
 *
 * Derivation minted here, flagged for the eye (the built sheet declares no
 * dark partner): --_dk-link-teal collapses onto the dark teal per ruling 1's
 * collapse clause ("the darker text-teal step deliberately collapsing onto
 * it in dark" — link teal is a darker teal text step).
 *
 * Gate: site/tests/run.mjs ("site token layer" tests — values byte-exact to
 * the Decision's text, corrective swap executed, dark-selector remap parity,
 * artifact name-collision sweep, ruled contrast floors computed). */
