The mark is now a feathered hat with an arc of eighth notes, traced from the operator's reference artwork at 99.74% IoU. The hat takes the text colour and the note arc holds the accent — the same construction the M used, and for the same reason: parchment on a light surface is invisible, so the silhouette has to flip with its background while the accent stays constant. This reverses the subject-neutrality argument recorded in Minstrel's design system, which held that depicting a bard would tell a new user the app is for renaissance-faire music and had twice rejected a hat. The operator commissioned this artwork and chose it with that objection on the table; the record is updated rather than silently contradicted. Both accent-filled alternatives were measured and rejected: #4A6B5C is 3.04:1 on obsidian and 2.80:1 on the raised iron, so an accent hat drops under the 3:1 graphics floor as soon as it sits on a card. tools/gen-brand-assets.py is the single source for the four copies, which cannot share a file because each needs a different colour mechanism — currentColor inlined, a prefers-color-scheme swap in the favicon, literal fills in mark.svg, flat pixels in the rasters. Hand-copying 20KB of path data four ways is how a silhouette change lands in three of them. Two notes on the trace, both non-obvious: it runs on the original antialiased greyscale rather than a binary mask, because tracing a supersampled mask scores ~100% IoU by reproducing the pixel staircase exactly — a perfect number for jagged art at 120KB of path, versus 99.74% at 20KB. And potrace reads PBM where bit 1 is black, so the ink mask is inverted going in; backwards, it traces the background and still emits a plausible-looking SVG. The header lockup moves 20px → 28px: the hat carries far more detail than the M and does not resolve below ~32px. The 16px browser-tab favicon is still a blob at that size and is not addressed here.
