/* Recipe → Grocery List
 * Two panes: recipes go in on the left, one aisle-grouped list comes out on
 * the right. The signature is the aisle sections — each with a colored tab —
 * that make "sorted for the store" the thing you see first.
 * Type: Bricolage Grotesque (display) + Inter (body). Aisle colors from the
 * validated dataviz categorical palette (one fixed hue per aisle).
