/* ib-guide.css — the guide-page stylesheet, in ONE place.
   ---------------------------------------------------------------------------
   This 78-line block was byte-identical (after whitespace/comment normalisation)
   in 142 of the 148 pages under public/legacy/guides/. It was duplicated 142
   times: ~11,000 lines of copy-paste. It now lives here, once.

   NOT linked by the 6 pages that never carried it: the five "hybrid" guides
   (trt-guide, semaglutide-dosing-guide, tirzepatide-dosing-guide,
   bpc-157-peptide-guide, bpc-157-tb500-blend-guide) and the guides index. They
   carry a DIFFERENT block that mixes calculator typography into the guide layout.
   Do not link this sheet there without diffing their block against this one.

   Named ib-*.css so next.config.ts's no-cache header applies (see ib-shell.css).

   ORDER IS LOAD-BEARING: linked immediately BEFORE /ib-shell.css, which is the
   position the inline <style> occupied. ib-shell.css therefore still wins the
   equal-specificity ties it used to win (notably html,body{background}). Moving
   this link after ib-shell.css would invert that.

   Every background here resolves through var(--bg); no colour is hardcoded, so
   the one-line background change in ib-shell.css still governs these pages.
