| 4 | // Dock without inventing a new mark (CLAUDE.md: never hand-roll a |
| 5 | // substitute glyph). Two variants: "dev" (orange, the default) and "live" |
| 6 | // (green — the convention for a dev build aimed at PRODUCTION home, so two |
| 7 | // running alts with different aims never share an icon). Run from the repo |
| 8 | // root: |
| 9 | // |
| 10 | // swift tools/make-dev-icon.swift # AppIconDev (orange) |
| 11 | // swift tools/make-dev-icon.swift live # AppIconDevLive (green) |
| 12 | // |
| 13 | // Committed output; re-run only if the canonical icon changes. |
