1. Scroll felt "stuck": the seen-by card had TWO nested scroll containers
(.modal overflow-y:auto + inner .seen-scroll) fighting each other — card is
now overflow:hidden so only the inner list scrolls. Global scrollbar widened
6→11px, dropped the inset border, added a min thumb length so it's easy to
grab and drags smoothly everywhere.
2. Group message toast now carries a generated group icon (initials on a brand
disc) when the group has no photo — was iconless.
3. Seen / Not-seen split by a visual divider in the message-info popup.
4. Auto-correct: curated common-typo dictionary applied as you type (on a word
boundary) — corrections happen automatically, no right-click. Web/desktop/mobile.
