DoughCalc v19 deployed: new Add-ins card - dropdown of common extras (garlic, herbs, cheese, seeds, etc.) or type-your-own manual entry, amount+unit, Add button builds a running list with per-item remove. Persists in local device state across opens like the rest of the screen. When bake notes are saved to the log, add-ins are automatically folded into the context line so they're captured with the bake record. JS syntax validated before deploy.
