/* Shared styles for the Mills blog (blog/*.html). Loads after products/product.css,
   which supplies the nav, footer, eyebrow, buttons and tiles. This file adds the
   two-theme token layer, the prose column, and the figure kit that posts build on.

   Dark is the default and matches the rest of the site. Light is opt-in per reader
   (blog.js, stored under mills-blog-theme) and takes its palette from the Atlas app
   style guide: warm off-white surfaces, stone text, teal accents. Every color below
   is a token so a figure written once renders in both. */
