/* blog.css — the single stylesheet for everything under /blog/.
 *
 * Why one file: every post is hand-written static HTML with no build step (D8).
 * If each post carried its own <style> block, a design change would be an N-file
 * edit and the pages would drift apart the way the six root pages drifted off the
 * font system in R&R-129. One stylesheet means one place to change.
 *
 * Tokens are copied from index.html's :root so /blog/ and the money page agree.
 * The two font tokens must stay byte-identical to the strings in
 * scripts/verify-fonts.mjs — that script is the guard for R&R-129.
 *
 * Root .html pages are NOT governed by this file and must not link it. HS5:
 * their URLs and markup stay exactly as they are.
