   MEAL CALCULATOR — search and meal building.

   Scoped under .meal-page. BMR and BMI are a form plus one number; a meal is
   a list the user builds, so this needs its own layout rather than the
   .calc-form / .calc-result pair. It still uses the same tokens and the same
   accent-override mechanism, so it reads as the same product.
