Step 2 — Author (pptx-author)

Write the deck as markdown where every slide names the exact template layout it should land on, using [HINT: layout_name]. This is the bridge between "I know my template's layouts" (Step 1) and "render the deck" (Step 3).

You are here: Step 2. You need the layout-catalog.md from Step 1 (or use the bundled Inner Chapter layouts). Output is a slides.md the renderer consumes.
