/* ============================================================
   Smart V Learning Centre — v2 redesign (claude-v7-20260610)
   Direction: 精裝校簿 editorial trust.
   Paper-and-ink stationery feel: deep Smart V blue as the trust
   anchor, serif display headings, notebook-grid texture echoing
   the Higgsfield ambient loop, yellow reserved for conversion.
   v7 polish: stationery details (label-sticker kickers, washi
   tape on the proof board, ruler progress bar, marker sweeps),
   poster lightbox, per-section reveal variants.
   ============================================================ */
