On the tall composer (iPad, and the sidebar tab-picker layout), the dictation confirm button sat flush against the composer's rounded right edge, while the send button in the same spot is inset.

The send button (ComposerActionButton) puts its 44pt circle in a 62pt-wide slot, which keeps the circle 9pt from every edge and concentric with the 31pt corner. VoiceActionButton used a 44pt slot. It now uses the same slot width, circle size, icon size, and Android font scaling as the send button. While aligning the other composer types:

• The stop / resume / send buttons shown inside the dictation toolbar were never given size, so on iPad they rendered at phone size next to a large confirm button. They now follow usesLargeControls.
• The dictation toolbar's bottom offset (2) ignored the Android floating-sidebar composer's 6pt padding, so it sat 4pt lower than the draft row. Both now read one surfacePaddingVertical.

The phone composer's geometry is unchanged apart from Android font scaling.

Evidence: none yet. The Mac Mini device host currently has no simulators, so I could not capture before/after on iPad or iPhone. Format, lint, knip, and typecheck pass (vp run check:changed).

Walkthrough

The composer now derives its vertical surface padding from control and sidebar settings and reuses it to position the dictation toolbar. Dictation action sizes follow the large-controls setting, and action button dimensions use Android control scaling.

Changes: Dictation Control Sizing

Layer / File(s)	Summary
Scale dictation action buttons apps/mobile/src/features/voice-input/ComposerDictationControl.tsx	VoiceActionButton applies Android control scaling to circle and icon dimensions. Large primary buttons use a 62-point-wide pressable container.
Align composer and toolbar sizing apps/mobile/src/features/threads/ThreadComposer.tsx	The composer uses surfacePaddingVertical for surface padding and toolbar position. Stop, resume, and send actions receive a size based on usesLargeControls.
