Every top-level :::name block is now a tab, shown in file order, so
authors can add custom tabs and reorder them in the markdown. Titles
come from the name or a :::name[Title] label.
The recipe card is an ordinary :::card tab. Its body lists what it
prints (::ingredients, or a block written just for the card), replacing
::card, the fallback to full sections, and its fixed tab position.
All recipes are migrated, with pages and card images unchanged.
