Generated a transparent PNG set from the source icon (a JPEG with a baked-in
checkerboard) by keying out the background on saturation — the arrow is
strongly saturated (0.47-0.68) while the grey/white background is 0.00, so
the cutout is clean. Produced static/logo.png (top-bar, natural aspect),
static/favicon.png (32px), and static/apple-touch-icon.png (180px).
Wired favicon + apple-touch links into all three page heads (feed, settings,
login) and placed the logo next to the "AgentFeed" title in the top bar.
