Gallery: a blocked note wraps beside its dot

blocked() laid its text as a flex item beside the dot, and gpui measures
a text item's least width unwrapped, so a long note ran past its column
and the dot shrank to nothing. The text now sits in a flex_1 block with
no least width beside a dot that never shrinks, which rests on the first
line, as Alert holds its icon. The a11y note and the motion page's
Lottie note wrap inside their columns. A failed hue check names both
charts in hex.
