Pull request overview
Adds condensed-density styling support for the Messaging UI by introducing data-slot hooks in Messaging components and new condensed overrides in condensed-view.css, aligning Messaging with the repo’s existing condensed-mode pattern.
Changes:
- Added
data-slotattributes across Messaging components (thread, header/list items, message list/bubbles, composer, attachment picker, lightbox) to provide stable styling hooks. - Added a new “Messaging – condensed overrides” section to
src/styles/condensed-view.csscovering header, conversation list items, message list states, bubbles, and composer layout/alignment. - Adjusted condensed composer layout (centering/alignment + textarea/character counter positioning).
