What problem does it solve? Inconsistent overflow menus in Husi's Compose topbars lead to broken shapes, fake clickable title rows, and compile errors from mixing up shape and shapes parameters. This Skill encodes the house conventions so every more_vert actions menu inside CapsuleTopBar or CapsuleSearchTopBar follows the same Material3 Expressive pattern. ## Core Features & Use Cases - Standard menu structure: Wraps the overflow icon in CapsuleActionButton, uses DropdownMenuPopup with DropdownMenuGroup, and applies MenuDefaults.groupShape and MenuDefaults.itemShape for grouped rounded corners. - Section headers done right: Replaces fake clickable title rows with the shared DropdownMenuSectionHeader helper, and clarifies that headers do not count toward item shape indexing. - Correct shape APIs and interactions: Distinguishes shape for plain onClick rows from shapes for selected/checked rows, and covers checkbox filter rows and dismiss behavior. - Use Case: When adding a sort-mode menu to a topbar, apply checked DropdownMenuItem rows with MenuDefaults.itemShape(index, count), a DropdownMenuSectionHeader label, and verify with ./gradlew :composeApp:compileKotlinDesktop. ## Quick Start Add a more_vert overflow menu to this screen's topbar actions following the husi actions dropdown menu conventions with grouped items and a section header.
