/*
 * This Yet That — app layer on the Understanding Workbench design system.
 * Load AFTER workbench.css (the canonical design-system.css, pasted verbatim).
 *
 * This file does two jobs:
 *   1. Maps the app's interactive chrome (forms, buttons, cards, header
 *      offsets) onto the system's semantic variables (--text-1, --wash-1,
 *      --line-1, the palette tokens). No literal colors except rgba washes
 *      of palette tokens, matching the system's own practice.
 *   2. Defines legacy alias tokens so page-specific CSS written against the
 *      earlier app vocabulary (--primary, --font-headline, --radius, …)
 *      resolves to workbench tokens. New page CSS should use the workbench
 *      names directly.
