a11oy landing: strip remaining jargon from user-facing copy per honesty rules (no greek/internal symbols in marketing text) — 'Trust score (lambda-symbol)'->'Trust score', formula 'lambda-Cone Monotonicity'->'Trust-Floor Monotonicity', footer line now reads 'TRUST SCORE = RESEARCH CONJECTURE (NOT A THEOREM)'. pages/landing.html only; no serve.py / console.html change.
a11oy: add investor-grade marketing landing at /landing (pages/landing.html) leading into the live command console; register the /landing route inside the already-imported a11oy_frontier_patch.py (NO serve.py / console.html edit). Animated orbital brain, live KPIs from /api/a11oy/v1/* (services-up, trust score, gates), shared SZL house style.
