/* Ponte News: the reader design (spec section 7).

   Calm and plain: soft off-white page, deep blue-grey text, one gentle teal accent, alerts in muted amber
   (never flashing red), a readable serif for headlines and a clean sans-serif for summaries, one column.
   Dark mode follows the reader's device setting.

   Colours are named once below ("tokens") and used everywhere else, so a colour changes in one place.
   tests/test_design.py reads these tokens and checks every text colour against its background for
   WCAG 2.1 AA contrast (4.5 to 1), in light and dark mode. Change a colour, run the tests.

   No web fonts: the font stacks use fonts already on the reader's device, so the page loads fast and no font
   service learns who reads Ponte News. */
