Tauri's macOS bundler validates that every PNG referenced from
src-tauri/icons/ is RGBA. Our previous rebuild-icons.py wrote RGB PNGs
because the trim/pad pipeline lives in RGB to keep transparent edges
out of the glassy logo. macOS build failed with:
error: proc macro panicked
--> src/lib.rs:1073:16
message: icon /.../desktop/src-tauri/icons/32x32.png is not RGBA
Fix: scripts/rebuild-icons.py now does `.convert("RGBA")` on every
PNG output before saving. Alpha is fully opaque (255) — the rounded
glass edges retain their look on any background since we paint on
solid white in load_trimmed_square. Same files keep working for
Windows .ico embedding (which accepts RGBA fine).
Regenerate all 17 PNG outputs (32/64/128/128@2x/icon.png + 9 Square*
+ StoreLogo + public/app-icon.png) and the derived .ico/.icns.
Mac side: pull this commit and re-run `bun run build:macos-arm64`.
Windows side: no change in behavior (Tauri's NSIS bundler doesn't
care about PNG color mode).

User-supplied screenshot of the Heicode H circuit logo (heicode-logo.png
at repo root) was background-removed via flood-fill from the image
borders, edge-feathered with a 0.7px Gaussian on the alpha channel, and
upscaled to 1024x1024 as the master.
Replaced everywhere the icon is referenced:
src-tauri/icons/
32x32.png, 128x128.png, 128x128@2x.png — Tauri build inputs
icon.ico — multi-res 16/24/32/48/64/128/256 (Windows installer +
taskbar)
icon.icns — multi-res 16/32/64/128/256/512/1024 (macOS bundle)
Square*.png + StoreLogo.png — Windows store sizes (kept in sync)
public/app-icon.png — splash icon shown by HeicodeLoginPage,
ActiveSession.tsx, EmptySession.tsx,
Settings.tsx (1024x1024)
The H mark sits on transparent alpha now; on dark window chrome it
appears as the floating logo without a white card. Source resolution
(273x276) means 16/24px renderings are slightly soft; adequate for
taskbar/tray and crisp at 32px+.
