the project lead's rule, 4 October 2026: the mark sits in a black square, never in a circle, never on another colour, 20% clear
space; the Mac app is the model. brand/master/igneum-mark-square.svg (1024, #0C0C0E, the exact header polygons at 62%)
and igneum-mark-square-rounded.svg (Apple's 824-on-1024 grid, DMG volume icon only). make-icons.py now rasterises the
masters (rsvg-convert if installed, else Pillow draws the polygons) into igneum.icns (plain square, 16 to 1024),
igneum-volume.icns, igneum.ico (each size from the vector), the Inno art, the DMG background, site favicons
(favicon.ico 16/32/48, favicon-32, apple-touch 180, 192, 512, maskable 512 + manifest entry), relay favicons, and
brand/profile (400/512/1024, github-org-512, X banner). Every page head's inline SVG favicon and the relay header lose
the ring. The .rc and Info.plist paths are unchanged (same file names). docs/brand/before holds the old set.
