The bio mark — chords, offsets & the implied ∞

A single flowing ligature: b (stem + bowl), i (centre stem), o (right loop). The floating dot is the i's tittle — its alignment over the centre crest is the implied b→o connection. Drag the dot to test the tolerance; the plumb overlay re-measures live.

crest = top of the centre stroke (tangent horizontal). dx = dot centre − crest x · gap = crest → dot underside. drag the dot in the canvas.

implied ∞ · core lobes are 180°-symmetric about (142.5, 186.6) to ~3px median. spine x: bbox 141.3 · dot 141.9 · crest 142.6 · ∞-centre 142.5 (spread 1.3px).

axis · seg3 ctr (−110.8, 3.2) → heart → seg16 ctr (242.1, 232.0): a ~33° diagonal, but the heart sits 16.1px off it. to make them collinear, nudge seg16 by (−12.7, +17.5) → centre (229.4, 249.5). green ring = on-axis target. toggle implied ∞.
