Recipe Scaler & Converter

Doubling a recipe isn't doubling everything — spices, salt, leavening, pan size, and cook time all behave differently. Paste a recipe and a target (6 servings, a 9×13 pan, metric); it rescales every ingredient into sensible kitchen measurements, adjusts the non-linear items with a note explaining each, and re-estimates cook time and vessel size so dinner for twelve doesn't come out wrong.
