 * Palette is derived from the live brand mark (carbsnap-logo-light.png):
 * coral #FF8080 for the wordmark and both accent dots. The rest of the
 * site keeps that coral confined to the logo and uses the theme's stock
 * blue (#4582EC) for everything else — here it's promoted to the blog's
 * accent color (dates, hover states, the dot motif) to give articles their
 * own identity while staying unmistakably Carbsnap. Font stays Rubik
 * (site-wide, see base.html); heading weight/scale follows theme.css.
