- #5: use the ACTUAL brand C (extracted transparent white C + gold dot from the master
app-icon) on the blue headers instead of a hand-drawn mark; login card keeps the app icon.
- #3: read-receipt double tick on my own (blue) bubble is now brand yellow (was blue-on-blue,
invisible).
- #2: Sign-in button shows a spinner + 'Signing in…' on submit.
- #1: web notification uses the sender/group DP URL directly as the icon (drawing an external
DP to canvas tainted it → silently fell back to initials).
