/**
 * Sidebar styles. Per the DSH web-styling rules every visual value rides the
 * theme: --dsw-alias-* semantic tokens for colors, --dsw-font-* typography
 * roles (size paired with line-height), and --ds-* for motion. The chrome
 * mirrors the native DSH sidebar: flat (NO box-shadows anywhere), the
 * sidebar fill surface, hairline borders, and the 28/36px circular icon
 * controls with hover fills. No static palette values, no color literals, no
 * theme selectors — light/dark adaptation is the theme package's job.
