/* reference-page.css — the page shell for generated gem and reference pages.
 *
 * EXTRACTED 2026-09-18 from the CSS template literal in
 * scripts/generate_reference_pages.js, where it was inlined into every page
 * that generator writes: 132 gem pages plus the reference hub and the RI and
 * SG charts. ~121 rules x 135 files, so the shell design could only be
 * changed by regenerating, and could not be changed at all without editing a
 * JS string.
 *
 * This is NOT inner-page.css. The two groups have deliberately different
 * looks — here .section is a card (surface, border, radius, padding) and main
 * is 1200px; in inner-page.css .section is a bare margin and main is 1100px.
 * Pointing these pages at inner-page.css would redesign them.
 *
 * Loaded AFTER /shared.css and BEFORE any per-page <style>, which is exactly
 * where the inline block used to sit — so the cascade is unchanged.
 * PAGE-STANDARD.md sec 1.
