/* components.css — every reusable visual component. Tokens only from
 * theme.css; no hardcoded colors. Design language adapted from ostnoctua:
 * rounded surfaces, a soft accent glow on the active/focused state, small
 * uppercase section labels, monospace for numeric/technical values, subtle
 * transitions on interactive state changes (no continuous/decorative
 * animation beyond a busy spinner and a slow status pulse, mirroring what
 * ostnoctua itself does for "busy"/"slewing" states). */
