   One stylesheet, no build step, no CDN. The CSP forbids remote style, so
   everything the app needs is here.

   Colour comes from the data-viz reference palette. The chart surfaces are that
   palette's own documented surfaces (#fcfcfb light, #1a1a19 dark) rather than
   values picked to match this page — the palette's validation results only hold
   against the surfaces they were measured on, so changing them would silently
   invalidate them.

/* Nothing in this app should make the PAGE scroll sideways. Wide content
   scrolls inside its own box; this is the backstop if something escapes.

   axis to `auto`, which turns the body into a scroll container and breaks both
   the normal page scroll and any position:sticky inside it. `clip` leaves
   overflow-y visible. */
