Bricks and reusable composition

Foundry supports an alternate “bricks” structure:

bricks:
  hero:
    block: hero
    content: ...
  stats:
    block: stats-grid
    content: ...
bricks_order:
  - hero
  - stats

If sections is empty and bricks exists, Foundry will render bricks in bricks_order (or map order if not provided).

Use this when you want reusable named blocks and ordering without duplicating section objects.
