/* =========================================================
   Pi nebenbei — shared stylesheet
   Design language: light paper white, raspberry as the accent,
   teal for confirmation, amber as the only warning colour.

   Rebuild 07/2026 — guiding ideas:
   1. ONE text axis. Every section shares the same container so the
      left edge never jumps while scrolling.
   2. ONE line length (--measure) for all body copy.
   3. Density over length. Vertical spacing cut by about a third,
      callouts moved into the right-hand column.
   4. Two callout colours, not four: amber warns, neutral explains.
