Sticky Note Patch

Aggregate patch of small square sticky notes as one thin card-thickness piece, with a layout knob (tight grid on a wall, loose scatter on a monitor bezel, a single fat pad block) and a colour knob from yellow-only to a mixed accent-colour set.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
