/*
 * Time Is Luck — Blog stylesheet
 * Lives at /blog/blog.css on production. Loaded by every blog article and the
 * blog index. Also styles content injected by /blog/blog.js (header, footer,
 * method CTA partials) so layout reserves correct space before injection
 * (no FOUC layout shift).
 *
 * Single source of truth: edit this file, upload it, every page picks it up
 * on next view. No regeneration of articles required.
