/* bellhours.com – "Is the stock market open?" Two themes, chosen by the MARKET,
   not by the visitor: the regular session is open → light theme with the sea-map
   blue; the bell has rung → dark theme with the sea-map red. There is no toggle
   on purpose: the colour IS the answer. Palette lifted from the SeaTempMap SST
   raster (seatemp lib/theme/tokens.ts): blue 10 °C #0961bb / 13 °C #0a8fd1,
   red 30 °C #d73528 / 28 °C #ff6c44. Neutrals follow Apple's system colours. */
