// Days/Exercises/Sets in CreateProgramRequest each cap at max=500 independently
// (models.go), which doesn't bound their product across three nested levels — a
// request with 500 days x 500 exercises x 500 sets still passes those tags. This
// struct-level check enforces the total-rows bound (models.MaxProgramRows) that
// insertProgramDays's single-transaction processing actually needs, since
// db.DB.SetMaxOpenConns(1) means that transaction holds the process's only SQLite
// connection for the whole request. Mirrors controllers/workouts.go's init().
