/* Homepage stylesheet: the page's former inline <style> block, verbatim, followed
   by the v2 page-scoped design layer (DSE, 2026-09-05).
   Lives in an external same-origin stylesheet on purpose: thedataexperts.mx
   serves `style-src 'self'` with no 'unsafe-inline', so anything left in the
   page's inline <style> block is silently dropped there: 124 of the homepage's
   351 selectors existed only inline and never applied on that distribution.
   This file is linked from the page head, which build.py places BEFORE the
   shared engineering-log.css link, so the cascade for the duplicated rules is
   identical to when the block was inline. The v2 layer at the end is scoped
   under body.home-v2 and wins on specificity regardless of position. */
