/*
 * Course detail pages (Google Ads, Meta Ads). Every rule is scoped under .cd / .cd-* so nothing else on the site changes.
 * Palette and fonts follow the site: #1560A8 primary, #1E8449 green, #F59E0B amber, #1F2937 charcoal, #F8FAFC off-white.
 * The whole page works without JavaScript (every class shows its full detail); course-detail.js adds the interaction.
