/* Pipa Academy (đàn tỳ bà): rosewood lacquer, ivory soundboard, lotus and gold.
   Signature shapes: the pear-shaped body of the tỳ bà (photo frames), its four strings and its frets.
   Everything is scoped to .tb-page / .tb-* modals / the two Pipa body classes so other instruments are untouched. */
