/**
 * Shared lender-page polish — Phase C of /root/COMAU_AWARD_DESIGN_PLAN.md.
 *
 * Loaded only on /lenders/* routes (motion.php detects URI). Operates on
 * the existing lender-page markup without editing per-lender files:
 *   - .breadcrumb     — first nav inside .lender-wrap
 *   - .versus-row     — the 12 round cards
 *   - .four-way       — 4-cell comparison grids inside each round
 *   - .lender-card    — directory cards on /lenders/
 *
 * Choreography starting states (GSAP timelines run from lender.js):
 *   .versus-row       — translate-y on viewport entry
 *   .lender-progress  — sticky pill, ticks up as rounds pass
 *   .breadcrumb       — auto-hides on scroll-down, shows on scroll-up
 *   .four-way mobile  — 2×2 grid with tap-highlight cell
 *
 * IMPORTANT: per-lender pages each declare their own brand colour via
 * a `:root` block (--anz, --nab, --cba etc.). This file uses only
 * site-level tokens (--sage-600, --paper, --ink) so it doesn't fight
 * the per-page colour identity.

/* ===== Sticky breadcrumb =====
   Sits below the (also sticky) site-header. Header height ranges from
   ~52px (mobile) to ~62px (desktop) depending on viewport — `top` value
   uses a CSS variable so per-viewport JS can override at runtime if the
   visual gap drifts. Default 56 covers most desktop renders. */
