/**
 * EDDA — FORMS + MODALS + AUTH PRIMITIVES
 *
 *  Plan 03 — Full rewrite against Edda design tokens.
 *
 * Contract:   Form field primitive.
 * Tokens sourced from css/edda.css :root block (promoted in Plan 01, consolidated in Plan 07).
 *
 * Load order on every auth entry page:
 *   edda.css (tokens) → forms.css (primitives) → animations.css → page-specific.css
 *
 * Any drift between this file and  (and its locked CSS target
 * block) is a spec violation. Do not reintroduce  tokens, shadows,
 * or rounded corners greater than 2px.
