/* SUPNPABLO WEATHER — "Signal Desk" design system
   Adapted from willcodexquotareset.com: near-black canvas with a faint grid
   texture and one big orange glow, hairline-bordered flat panels, a single
   loud accent (#ff5033) with violet/peach secondaries, tiny monospace
   eyebrows, and oversized tight-tracked display headings.
   Light mode is the paper edition of the same language. */
