/*
 * Brainwave journal visual refresh.
 *
 * Additive only -- never edits css/main.css or css/dept.css (shared by
 * the rest of the university site), so nothing outside brainwave/ pages
 * is affected. Every rule is scoped under body.bwj-page so even generic
 * Bootstrap/global class names (.point, .overview, .bg-light, etc.)
 * can't leak onto non-Brainwave pages that happen to reuse them.
 *
 * Palette is sourced entirely from the university's own existing brand
 * colors (confirmed in css/main.css): primary blue #0f3db8 and its
 * tonal family, accent orange #f77a10. Nothing new introduced -- just
 * used more deliberately (gradients, soft tints, shadows) for a more
 * current, student-friendly feel while staying on-brand.
