One concept throughout: the reveal panel, miniaturised. Empty left, three category marks right, the drag handle on the seam. Only proportion, weight and corner treatment differ.
A — proportion
Slightly wide tile, seam off dead centre, marks optically balanced rather than evenly spaced.
B1 — heavy frame
Frame at 4.5, seam at 2, handle outlined. The tile is the object.
B2 — heavy seam
Frame at 2.5, seam at 4, handle blooming in cyan. The split is the object.
C — corner ease
B1 weights with the smallest radius that holds at 16px without reading as an app icon.
A — quiet grid
Grid at 55%, short ticks, no bloom. Ad-heavy reading: 5 pink / 3 cyan / 2 amber.
B — registration marks
Grid at 35%, long ticks, handle blooming. Tracker-led reading: 3 / 5 / 1.
C — ruled paper
Grid at full weight, ticks tucked short. Sparse affiliate reading: 2 / 2 / 3.
note: the real reveal seam in the app carries no handle and no glow, so the bloom above is the same cyan bloom already used on the landing page's one accented control — no new value was introduced.
