/* Chess of the Hundred Guardians — interface styles.
 * Visual language follows the Amaravati Cyber design system: limestone by day, neutral graphite at
 * night, the rust accent for what can be pressed or is selected; opaque surfaces, hairlines and soft
 * shadows; serif headings, a clean sans body, tabular numbers. Fonts are the system fallbacks of that
 * system's stacks (no font files are loaded). Nothing animates behind reading text: the arena canvas
 * shows only on the home screen and during play. */
