// MOONSHOT — level (inning) definitions.
// Pure data module: no three.js, no DOM. Consumed by game.js and main.js.
//
// Field contract (physics.js createPitch reads these):
//   name     — display name, chunky uppercase
//   tag      — short modifier tag for UI chips/logic
//   hr       — home runs required to clear the inning
//   pitches  — pitch budget for the inning
//   duration — nominal pitch flight time, seconds (lower = faster/harder)
//   speedVar — ± fraction of duration randomization per pitch
//   curve?   — [lo,hi] lateral break amplitude range (meters at plane)
//   jitter?  — [lo,hi] vibrational wobble amplitude range (meters)
//   blurb    — one-line flavor for the intro card
//   mods     — modifier chip labels shown on the intro card
//
// Difficulty shape (monotonic-ish, nine innings — R7, durations R20):
//   L1 tutorial mercy: slow, no curve, no jitter, generous 3/8.
//   L2 pure speed. L3 introduces the curve (a touch slower — new skill).
//   L4 mild jitter. L5 jitter + light curve combo. L6 fast + big break.
//   L7 fastest-yet + heavy break + wobble. L8 a breath of slack (4/9)
//   before L9 EVENT HORIZON: everything, everywhere, all at once, 5/9.
//   Every inning is clearable by perfect play: hr <= pitches always.
//   R20: durations cut hard for the real-scale 60.5-ft mound — pitches now
//   fly release→plane (18.44 m) in ~0.4–0.6 s, roughly MLB pace.
