Walkthrough

Mobile navigation now uses a centered icon dock with responsive sizing and scroll-based compact mode. The dock can include a commit button. The lite mobile app continues to render supplied children and its tab component.

Changes: Mobile navigation dock

Layer / File(s)	Summary
Dock controls and child separation resources/js/components/app-nav.tsx, resources/js/layouts/app-layout.tsx	MobileCommitButton supports floating and docked styles. MobileNav separates the commit button from other children and counts it as a dock item. AppLayout sets the button’s floating state from the lite-app state.
Responsive dock behavior and rendering resources/js/components/app-nav.tsx	MobileNav tracks scroll direction and adjusts compact mode. A resize observer sets the navigation height, dock scale, and inset. The standard mobile navigation renders dock controls and a menu. The lite-app branch renders supplied children.

Merge Risk: Low · up to df8cd

The dock remains usable, but can show a blank slot and does not compact while scrolling Remotes. These are limited visual regressions; the change is mergeable with owner awareness.

Review comments at @resources/js/components/app-nav.tsx:
- Line 577: Update the child-control check in the component that computes
itemCount: the children passed by app-layout.tsx may be an array containing only
false values, so a truthy check reserves space and renders an empty cell.
Determine whether any child actually renders, use that same result for itemCount
and the conditional cell near line 777, and add the required React import while
preserving layout spacing when no controls render.
- Line 538: Update the lite-app branch of the mobile navigation so the compose
button rendered by MobileCommitButton floats above the native tab-bar area
instead of occupying its top-left corner, and has a visible surface. Give that
branch its own positioning and styling or an equivalent branch-specific
override, while preserving the dock branch’s existing button layout.
- Around line 777-787: Render the app suggestion represented by children as a
sibling of the dock within the nav, outside the 44px slot and its itemPosition
placement; restore pointer events on the suggestion card so its store link and
dismiss button are tappable. Keep the commit button in the dock slot.

Measure the lite-app nav without a dock surface.

In the lite app, dock.current is null. This guard returns before the observer sets --mobile-nav-height. The toaster and conversation layout then use their 4.5rem fallbacks instead of the lite nav’s measured height. Measure element in both branches. Calculate dock sizing only when surface exists.

Review comment at @resources/js/components/app-nav.tsx around lines 663 - 664:
Update the observer logic around the `element` and `surface` null checks so it
measures `element` and sets `--mobile-nav-height` even when `surface` is null.
Keep dock-size calculations conditional on `surface` being available, and
preserve the existing behavior when both are present.
