`assets/icon.png` — presence is the declaration, so this takes over the dock tile
from the lucide `PenLine` name in the manifest. no manifest change: a file that
is there is the whole mechanism, and there is no field to keep in step with it.
256x256, matching every other plugin's icon rather than the source's 300.
TRANSPARENCY SURVIVED THE RESIZE, which is the part that needed care: the source
is half fully-transparent pixels, and a resize without `-background none`
composites them onto white — a black logo on a white square, on a dark dock.
checked after: alpha min 0, top-left srgba(0,0,0,0).
encoding chosen by measuring rather than by habit. straight PNG32 came out at
44 KB — LARGER than the 300px source — because a forced 32-bit RGBA gets no
palette. PNG8 is 7 KB and bands the anti-aliased edges (RMSE 404). pngquant at
quality 90-100 is 15.5 KB with RMSE 68, six times more faithful than PNG8 and a
third the size of full colour.
