- Removed difficulty categorization entirely (type, badges, styles) —
cleaner and no arbitrary skill labels.
- Added many requested/missing tricks with proper research and correct
alt-names, including:
• Rotations category: FS/BS 180, FS/BS 360, half-cab, full cab
(caballerial), fakie 180s.
• Flip tricks: backside flip, frontside flip, FS/BS heelflip, double
heelflip, 360 hardflip, 360 pressure flip.
• Grinds: feeble grind now notes "Grosso grind" aka; added Willy/
Barley, pole jam; inventor credits (Suski, Losi, etc.).
• Fundamentals: nose ollie/north, one-foot, no-foot/nothing, nose
manual, caveman, tic-tac.
• Shoves: nollie shove, ghetto bird.
• Grabs: tailbone, airwalk. Stance/slang: pop, line, kook, sticker
slap, etc. Hardware: durometer.
- Updated the local glossary answerer index to cover all new aka names
(e.g. "grosso grind", "half cab", "north ollie" now answer locally).
