/* The owner's dashboard. A plain, quiet admin (owner, 2026-10-06: «простая современная админка», our own sheet,
   neutral look): greys, one accent — the brand's sun — and three tones for states. Modern CSS only, no framework, no
   build: cascade layers, nesting, oklch and light-dark() for the dark theme. Served from the dashboard's own origin
   (CSP style-src 'self'); the templates carry no style attribute. */
