Learn

Short tutorials on getting good at takeoff — measuring well, annotating clearly, and reading a bill of quantities.

learn.emptyState

⚠ Graceful omission: renders an honest empty state while no article exists. Never a 'tutorials coming soon' hole in an otherwise-complete grid.

learn.categoryGrid

Category grid + featured tutorial + search. Renders from the learn source; empty categories are omitted, not stubbed.

learn.mdxPipeline

FOLLOW-UP (own turn): switch the article source to MDX under src/content/learn/*.mdx per §2.8. Needs @next/mdx + a build-config change, so it is not an additive skeleton change.
