/* pult.watch/energy (Kir, 27.10.2026). Only this page loads the file (templates/site/energy.html, block "pagehead").
   Fonts are the ones our product sites share: Unbounded for headings and big numbers, Onest for text (as in the Pult Energy app and
   cabinet, Kir 27.10), JetBrains Mono for telemetry (W, kWh, times). All self-hosted, OFL (static/fonts/Brand-OFL.txt): the hub's CSP is default-src 'self'.
   The background is the light at home, as in the Pult Energy app (pult-energy/docs/design/TOKENS.md): a mint aurora
   while the grid is on, a warm red one on the battery. energy.js switches .e-page[data-grid]. */
