Charcoal field #1B1D21 -> #211D1B, accent #4C7DF0 -> #B8862E across all 6
apps in the family, matching the unified-design-system palette rework
already applied to diet-guard/dufs-cloud/screen-locker/gatelock. Both are
exact byte-reversed mirrors of the old values, so relative lightness is
unchanged -- only the tint shifts from blue toward red/brown.
Also fixes stale prose in README.md left over from an earlier accent-
unification pass (claimed each app had its own accent; they've shared one
since that pass).
Verified: 39/39 tests, preview contact sheet reviewed, all 6 repos'
assets regenerated (diet-guard's rebuilt APK pixel-verified on device).
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.
