   browseML's page. The palette is defined once, here, for both themes:
     candle green  — Send, and positive events (✓ receipt, model verified, delivered)
     bitcoin orange — working states (downloading, reading, streaming), the active answerer, focus rings
     stop red      — failure (✗ receipt, errors, no delivery); the chart's red candle, kept in one variable
     term green    — T mode, terminal green on black
   The brand colours fill buttons, borders and rings as given. As text on the light theme's white they are too faint
   to read, so the *-ink tokens there are darker shades of the same hue. */
