/**
 * Codantrix Labs — shared stylesheet for /work/<slug>/ case study pages.
 *
 * Documented exception to the "inline <style> per page" rule in
 * .claude/skills/codantrix-site/SKILL.md. The rule still applies to every
 * top-level page (home, /book, /studio, /founder, /privacy, /terms, /404).
 * This file exists ONLY because the 5 case-study detail pages share an
 * identical template — inlining would duplicate ~3000 lines across them.
 *
 * Do NOT add styles here that aren't shared by all case-study detail pages.
 * Do NOT load this from any other page on the site.
