/* Wordmark is a single image, not type + an image side by side. The script
   "Alloy" is the real brand mark lifted from alloy-logo.png (tagline cropped
   off); "Techs" is Manrope 600 baked into the same PNG so the two are locked
   together and cannot drift out of baseline alignment across browsers or
   while the webfont is still loading. Regenerate rather than hand-tweak: see
   CLAUDE.md. Transparent background, because the nav is transparent at the
   top of the page and only goes solid on scroll. */
