/*
 * PawManual Calculators — calculator styles.
 *
 * Plain, self-contained CSS: no Tailwind, no theme dependency. Every selector
 * is scoped under .pm-calc so the calculators render correctly under any theme
 * and never leak styles into the surrounding page (CLAUDE.md §5, §6).
 * Visually matched to ThePawManual's neutral, rounded look.
