/* ══ The madlib intro: the home page's first screen (2026-09-26) ══
   Design handoff docs/design_handoff_jamyard_madlib_intro, high fidelity:
   colors, type, sizes, and timings are the handoff's. The sentence is
   authored on a fixed canvas (1280 by 440 wide, 640 by 640 stacked) that
   shared/madlib-intro.js scales to the container. No border radius
   anywhere: the corners are cut. */
