Igneum brand assets

The rule (Josh, 4 October 2026)

One global logo for apps, profile pictures, favicons, everything. The mark sits in a black square. Never in a circle. Never on another colour. Minimum clear space = 20% of the square. The Mac app icon is the model: a full square, all black, the mark in the middle.

• Square: #0C0C0E (the site's obsidian token, --obsidian in site/index.html).
• Mark: #F2541B ember, the flame's centre cut in obsidian. Geometry = the two polygons in the site header (site/index.html, 100 x 100 viewBox). Do not redraw it.
• Mark height = 62% of the square (so 19% clear on top and bottom, 30% on each side).
• No ring, no border, no rounded corners baked in, apart from the one rounded variant below.

Masters (brand/master/)

File	Use
igneum-mark-square.svg	The master. 1024 x 1024, full-bleed obsidian, mark centred. Every derivative comes from this.
igneum-mark-square-rounded.svg	Apple's icon grid (824 x 824 shape on the 1024 canvas, continuous corner as a superellipse). Only for the DMG volume icon. Tahoe masks the plain square itself, so the app bundle ships the plain square.

Generator

python3 brand/icons/make-icons.py rebuilds every file below from the masters. It uses rsvg-convert when installed (brew install librsvg), otherwise Pillow draws the master's polygons at 4x to 16x supersampling (exact, the mark is two polygons). The Windows .ico and the favicons render each size from the vector, never by shrinking a bitmap.

Inline SVG favicons (the data: link in every page head) carry the same square and mark, so a page shows the right icon before the .ico loads.

Not regenerated

• brand/igneum-coin-1024.png: the old ringed coin. Retired as a source; nothing reads it now.
• brand/igneum-mark-transparent-1024.png, the wordmark PNGs and Unbounded.ttf: unchanged.

Before and after

docs/brand/before/ holds the icons as they were (ringed coin everywhere except the GitHub avatar), docs/brand/after-*.png the new set.
