Poem

A dot now holds its tiny ground,
In flex it won’t be pushed around.
I thump my feet—precision met!
A tidy UI, no silhouette.
Hop hop, I sign this PR note—
A 10px dot, afloat! 🐇✨

54-69: Remove “fixes #8875” from the PR description
This PR only adds styling for ColoredDotIcon and does not modify any key‐handling or signup modal behavior.

61-66: Prefer longhand flex properties for clarity and type-safety.

Using flexGrow/flexShrink/flexBasis avoids magic-string shorthands and makes future tweaks easier.

65-66: LGTM: flex-basis freeze keeps the dot circular in tight flex layouts.

Setting flex: "0 0 10px" prevents shrinking and fixes the squashing. Looks correct and low-risk.
