Every Flutter app still shipped the stock Flutter "beach" launcher icon, and none had an adaptive-icon descriptor at all. Rather than hand-drawing five one-off icons, define the family once and let each app contribute only an accent colour and a glyph. The family: a charcoal #1B1D21 field carrying one glyph in that app's own theme seed colour, at a single stroke weight. Glyphs are optically centred automatically - render.centre_offset rasterises a glyph alone, measures its ink box, and translates (never scales) the fragment, so a row of icons lines up while every icon keeps the exact family stroke weight. safe_box_overflow warns when a glyph exceeds the 560px adaptive-icon safe box; it caught three real overflows that a launcher mask would have clipped. The registry points dufs_client at ~/dufs-cloud/app: ~/dufs_client was a stale, remote-less checkout with an identical package name, since deleted.
