Central vertex · one slider pushes every tile out · φ presets · adjustable ring.
1 unit = rhombus side. Vertices typed by angle: 36=1 · 72=2 · 108=3 · 144=4.

Goal: pull d until the ring's arc passes through the two type-3 vertices of
each fat tile, then nudge diamond +push so its type-1 tips just touch the same arc.
Tiles are exact unit rhombi — leg thickness is perfectly consistent by construction.
