Constants
-
kMultiAttachmentCardRadius
→ const double
-
Shared corner radius for every "card" inside a multi-attachment bubble —
grid cells (images/videos), audio rows, and file cards. Kept as one
constant so the curve of an image tile matches the curve of a file/audio
card exactly, across all four bubble types.
-
kMultiAttachmentContentInset
→ const double
-
Shared inset between a multi-attachment bubble's edge and its content
(grid / rows / cards) — 4dp on all sides, the same on every bubble type.
(2dp proved imperceptible against the light incoming-bubble background.)
