The app has an icon

Every build so far shipped the default Electron one. electron-builder said so on
every run — "default Electron icon is used, reason=application icon is not set" —
in a line that is very easy to read past. A store people install games with
should not look like a framework demo in the Dock.

The mark is a W with three lines running into it: the product's initial, and what
it is doing. It uses the window's own palette, so the icon and the application it
opens are the same object. Drawn for the smallest size first, which is what
settled it — at 32px the W still reads and the lines survive as motion rather
than as noise, where a ring, an outline or fine detail did not. A portal, a play
triangle and a send arrow were each drawn and each discarded: they already mean a
loading spinner, a media player and a submit button.

`resources/icon.svg` is the source and the only file anybody should edit.
`make icons` renders the rest. Three committed binaries with no way to regenerate
them is how an icon becomes something nobody dares change, so the ICO is written
here rather than shelling out to ImageMagick — the container is a header and 16
bytes per image, which is not worth a build dependency this machine does not
have.

`directories.buildResources` had to move off the default: electron-builder looks
in `build/`, which this project uses for compiled output and wipes on `make
clean`, so the icons would have been deleted before every package.

The window picks it up when run from source too, where there is otherwise nothing
to carry an icon and a dev run looks like a different application. Guarded on
`app.isPackaged`, because `resources/` is not inside the package and pointing at
it there would be a path that does not exist.

Verified by reading the icon back out of the built bundle rather than trusting
the config: extracted from `WarpEngine Client.app/Contents/Resources/icon.icns`
and looked at, and the ICO parsed entry by entry — 7 images, 16 to 256, each a
valid PNG.

+  what the W is doing — motion, read left to right, which is also why they are dimmer
+  than it is. Together they say "warp" without a spaceship, a portal or a play triangle,
+  each of which was tried and each of which turned out to mean something else already:
+  a send arrow, a loading spinner, a media player.

+  Drawn for the smallest size first. At 32px the W still reads and the lines survive as
+  a stack of motion rather than as noise; anything with an outline, a ring or fine
+  detail did not. The palette is the window's own, taken from src/renderer/style.css,
+  so the icon and the application it opens are the same object.
+
+  This file is the source. `npm run icons` renders every format from it; nothing here is
+  hand-edited binary.
