/* Prix de la Pomme: the whole stylesheet.

   Design choices (see docs/frontend.md, "Design"):
   - Plain, typographic base (from the v16 mock-up): white cards with a thin
     border on a soft page, left-aligned, system font. No glass, no map: the
     numbers are the content.
   - Colour where it carries meaning (from the original keynote design): every
     tile of the bento has its own hue (--tint), a faint wash of it at the top
     and a gradient big number. Green = cheaper, orange = pricier, blue = you.
   - Every colour is a custom property, redefined for dark mode, so the page
     follows the system theme without duplicate rules.
   - Dense tables over minimal layouts: visitors come to compare numbers.
   - Desktop first; tablets (900px) and phones (680px) at the end. */
