Quintine 8c19cdaae6 3D flight simulator: 6-DOF physics, three.js r160, browser HUD
- Detailed flight dynamics: aero lift/drag/side-force with smooth stall,
  control-surface moments, stability derivatives, engine spool with prop
  torque and gyro precession, inertial coupling, ISA atmosphere, ground
  effect, 3-point gear handling, landing vs crash classification.
- Pure ESM, zero build step; three.js vendored locally. Deterministic
  simulation; physics core is Node-testable (14 node:test cases).
- Procedural 8 km world with runway, water, sky dome, cloud wrap; DOM
  instrument panel (attitude indicator, tapes, VSI, lamps, stall warning).
- Controls: WASD/arrows, Q/E rudder, Shift/Ctrl throttle, F flaps, G gear,
  B brakes, C camera (chase/cockpit/orbit), R reset, P pause, D debug.

/* ============================================================================
flight-sim — HUD + UI stylesheet (integrator-owned).
----------------------------------------------------------------------------
CONTRACT for src/instruments.js (see README / INTEGRATOR_NOTES):
createInstruments(rootEl) creates ALL overlay DOM inside #hud using exactly
the class names below. No inline styles except dynamic transforms set per
frame (pitch/roll of the horizon, tape translations, bar widths, lamp glow).
Conventions:
.hud-debug — hidden by default (display:none); add .visible to show it.
instruments.debug(lines|null): null hides, array shows.
.hud-message — hidden by default; message(text, kind) sets text + kind
class (.info | .warn | .crash) + visible; clearMessage()
removes visible. autoHideMessageMs is applied by main.js.
.lamp — off-state lamp; add .on to light it.
.hud-stall — warning card; add .on (flashes) while data.stall is true.
========================================================================== */
