/*
 * Prisma Web — Design System Foundation v1.1.1 — Governance release
 * Purpose: shared design tokens and opt-in component primitives used by
 * selected administrative interfaces; this is not a global page template.
 *
 * GOVERNANCE:
 * - Ten administrative interfaces currently reference this same-origin file.
 * - Tokens use the --pw- prefix; component primitives use the .pw- prefix.
 * - Primitive classes affect only elements that explicitly opt into them.
 * - No global reset, element selectors, or overrides of legacy application classes.
 * - Extend adoption by page family only after focused review and testing.
 * - Keep semantic workflow and financial-state colours distinct.
