iblai-vibe-course-access

# /iblai-vibe-course-access  Add a full edX course-content experience -- hierarchical course outline sidebar, collapsible modules/lessons/sublessons with progress indicators, top tab strip (Course, Progress, Dates, Discussion, Instructor), breadcrumb + progress bar header, embedded learning MFE / LMS iframe with JWT postMessage handshake, previous / next unit navigation, timed-exam guard, and tenant-based access control. Pulls course metadata, outline, completion, and grading data via the data-layer RTK Query hooks. Do NOT add custom styles, colors, or CSS overrides to ibl.ai SDK components. They ship with their own styling. Keep the components as-is. Do NOT implement dark mode unless the user explicitly asks for it. When building custom UI around SDK components, use the ibl.ai brand: - **Primary**: `#0058cc`, **Gradient**: `linear-gradient(135deg, #00b0ef, #0058cc)` - **Button**: `bg-gradient-to-r from-[#2563EB] to-[#93C5FD] text-white` - **Font**: System sans-serif stack, **Style**: shadcn/ui new-york variant - Follow the component hierarchy: use ibl.ai SDK components (`@iblai/iblai-js`) first, then shadcn/ui for everything else (`npx shadcn@latest add <component>`). Do NOT write custom components when an ibl.ai or shadcn equivalent exists. Both share the same Tailwind theme and render in ibl.ai brand colors automatically. -...
