 * Evidence sources:
 * - accepted homepage reference composition (`style.css`, lines 6324–6363)
 * - accepted treatment/editorial variables (`style.css`, lines 5024–5173 and 5359–5855)
 * - accepted commerce/transaction variables (`style.css`, lines 4189–4192 and 4336–4340)
 * - accepted navigation and page patterns (`style.css`, lines 5960–6387)
 * - docs/DESIGN_AND_UX_PRINCIPLES.md and docs/ALLURE_COMPONENT_CONTRACTS.md
 *
 * These names are new and intentionally have no existing production consumer.
 * Introducing them therefore cannot restyle a current component. Future
 * component packages consume them through an approved component contract.
