How do I add a recipe to a specific day and meal in the planner?

Open /planner and tap the ➕ button on any empty slot (day + meal type). A drawer slides in with three sections — Inbox, Your cookbooks, and From the community — search across all of them, pick a recipe, and it drops into the slot. On desktop you can also drag a recipe card from the drawer straight onto a slot. Repeat until the week is planned.
