/* ==========================================================================
   Cascadia Deal Desk — page furniture.

   Layout carried over from cascadia.css in the Semiconductors module so the
   two read as siblings. The palette does NOT carry over: every token below
   is from the Cascadia design system v2.0. The old module's navy/blue tokens
   predate the system and are deliberately not used here.

   Rule 5.3: no text anywhere in a chart falls below 12px. Page furniture
   holds the same floor for consistency.
   Rule 5.7: light only. A dark palette would have to be separately authored
   and separately validated, so the page declares its scheme rather than
   letting the browser guess.
