/**
 * fixeo-modal-scroll-fix.css — fxmsf-v1a
 *
 * ROOT CAUSE FIX: fixeo-urgent-modal-v3.css fuv3-v1a contains:
 *   #request-modal.open { position: relative; }
 * This overrides main.css .modal { position: fixed }, detaching the modal
 * from viewport anchoring and causing the page to scroll behind it on mobile.
 *
 * ADDITIONAL: The entire .modal is the scroll container (header + content scroll
 * together), and iOS momentum scrolling propagates past the modal boundary.
 * Fix: modal = overflow:hidden container; shell = isolated scroll container.
 *
 * Applies to: #request-modal and standard .request-modal only.
 * Does NOT affect: dashboard fxv2-modal-overlay, comment-modal, content-modal,
 *                  express-modal (IIFE2 legacy), artisan reservation modal.
 *
 * Version: fxmsf-v1a — 2026-06-12
 * Load order: AFTER fixeo-urgent-modal-v3-patch.css (last in head)
