 * 01-tokens.css
 * ASW semantic layer — builds on Open Props
 *
 * Open Props (included by build.sh) provides the base scales:
 *   --gray-0…15, --green-0…12, --blue-0…12, --red-0…12, --yellow-0…12
 *   --size-1…15, --font-size-0…8, --font-weight-1…9

 *   --ease-1…5, --ease-spring-1…5, --ease-bounce-1…5
 *   --gradient-1…30, --animation-*, @keyframes
 *
 * This file defines only what Open Props doesn't:
 *   1. Surface / text / accent — semantic aliases (override to theme)
 *   2. Font stack aliases — prose, heading, ui (map to OP font stacks)
 *   3. Agent-native tokens — task, callout, session, wikilink, redacted
 *   4. A handful of precise values without direct OP equivalents
 *
 * To theme ASW:
 *   Override semantic aliases at :root in your own CSS.
 *   Use Open Props base tokens (--gray-*, --green-*, --size-*) as values.
 *
 * Lineage: absorbed patterns from Pico CSS, Open Props, Charts.css.

 *   data-chart-stacked                       — stacked multi-dataset mode
 *   style="--size: 0.8"                      — data injection on <td> (legal exception)
 *   style="--color: #hex"                    — per-row color override on <tr>
