Each phone is live. The category controls (the "level 2" you saw on desktop) surface differently per pattern. Tap around: the FAB / tab / dial opens the controls; in M1 tap a card to expand it, in M2 tap a dial item, in M3 tap a tab. Shown defaulting into Dimensions.
Tap a card in the sheet and it expands inline — exactly like desktop. Several can be open; the rest stay pills. Dimensions shown open here.
FAB ⚙ → sheet → tap a card to expand (accordion)
Tap a dial item and ONLY that category opens, full-screen-ish, with a ‹ back. Best when you want one job done with no distraction. Dimensions shown.
FAB + → dial → tap one → its focused sheet
The bar is always there; tap a tab and its sheet rises above it — controls one tap away, canvas always visible. Size (Dimensions) shown.
Tab → sheet rises · center FAB = Export
