/*
 * Shared foundation for every page. Light is the base palette and dark overrides it through
 * prefers-color-scheme, so no page has to redeclare a theme. Page styles consume these tokens
 * (`--surface`, `--surface-2`, `--surface-3`, `--border`, `--input-border`, `--border-strong`,
 * `--text`, `--muted`, `--muted-2`, `--accent`, `--accent-hover`, `--accent-ink`, `--link`,
 * `--selection`, `--danger`, `--success`, `--warning`, `--chart-grid`, `--shadow*`,
 * `--radius-sm` (controls), `--radius-md`, `--radius-lg` (panels), `--control-height`,
 * `--duration-*`, `--ease-*`) instead of hardcoding light-only or dark-only values.
