Name the app iPodderX and cut the icon's white background

A blanket white-to-transparent would have holed the device, whose body is
also white, so the background is flood-filled from the corners inward and
stops at the outline. Verified composited on the dark theme background
rather than by trusting the alpha channel.

The uppercase transform on the heading had to go too, or the name renders
as IPODDERX.

+## 2026-09-10 — App name, and a transparent icon
+
+Title is `iPodderX` in the browser tab and the sidebar. The heading's `text-transform: uppercase`
+had to go with it, or the camel case would have rendered as `IPODDERX`.
+
+The icon's white background is gone. A blanket `-transparent white` would have punched holes
+straight through the device, whose body is also white — so the background is flood-filled inward
+from all four corners at 12% fuzz, which only clears the *connected* region and stops at the dark
+outline. Then trimmed and scaled to 128px.
+
+Checked by compositing onto the real `#0e131b` rather than trusting the alpha channel: no white
+plate, and no pale fringe from the JPEG artifacts along the outline. The `.logo` rule lost its
+`background:#fff` plate and switched to `object-fit:contain`.
+
+Both files are tracked: `ipodderx-icon.jpg` is the untouched archival original, `ipodderx-icon.png`
+the transparent version derived from it, so the provenance chain survives. The PNG is embedded as a
+data URI for the sidebar mark and the favicon.

 ## 2026-09-10 — Colour scheme derived from the icon
 
 Palette sampled from `web/ipodderx-icon.jpg` with ImageMagick rather than eyeballed. The icon gives
