The composer starts as a single line with send beside it and grows only
when the text does; the shift-enter hint and the inline disclaimer are
gone. A typing indicator bubbles before the first token. The context
rail hides by default behind a toggle and stops scrolling sideways,
conversations open in the full view instead of a broken side drawer,
and the coach preferences move into Settings where the rest of the
configuration lives — context toggles and the exclusion list now derive
from one source so they can no longer contradict each other. A floating
bubble appears only while a coach-initiated nudge is unread. Clearly
stated allergies and conditions are remembered immediately through a
deterministic extractor instead of waiting for the twenty-turn
summary pass.
