 *   - Warn (Restart HA): amber. Reversible disruption (HA restart is
 *     ~30s and recovers).
 *   - Crit (Reboot): red. Irreversible-in-the-short-term action; matches
 *     ISA-101 alarm color = "operator must think before clicking."
 * If you change these to "all blue" or "all the brand color", you've
