   1. Design tokens

   These ramps started life as the Tailwind palette from the React source and
   did not match the rest of the site: a cooler navy for text and a violet-ish
   blue (#2563eb) for the accent, against index.html's #0d1526 ink and #0072f6
   blue. Every step below is now derived from the site palette in ../../style.css,
   which is linked ahead of this file on the blog pages, so `var()` references
   to it resolve here. Endpoints alias those variables directly; the in-between
   steps are interpolated so each ramp stays evenly spaced.

   Change a colour in ../../style.css :root and the blog follows.
