The mark shipped as an opaque 400x400 square, which reads as a hard tile
on the Manager's pack card. The frontend's PackBanner draws the icon
twice into a 7:3 box: once bg-cover plus blur(10px) at opacity-30 as a
backdrop, once object-contain on top. bg-cover crops to the centre and
zooms about 2.3x, so it samples mostly glow and lifts the surround to
~47, while the contained copy still shows the icon's own near-black
corners at ~17. Measured off a card screenshot, that is a 26-34 level
step at the tile edge; the same measurement on rgthree-comfy, whose icon
is a transparent SVG, is 2-3 levels.
Alpha now comes from luminance, which is the right derivation for
artwork that is additive glow on near-black, and it removes the edge
outright. Checked against a local reimplementation of PackBanner that
reproduces the screenshot's tile corners exactly.
The trade is that the pale mark washes out on ComfyUI's light theme.
Taken deliberately: the dark theme is the common case, and it is what the
comparable packs do. A dark backing disc was the alternative and reads as
a grey blob on light instead.
No version bump. The registry stores the icon URL rather than the bytes
and the Manager hotlinks it, so replacing the file on main restyles every
card; only a changed URL would need a republish. Also worth recording:
Banner is deliberately still unset, because PackBanner resolves
banner_url || icon, so a banner replaces the mark instead of sitting
behind it.
