2.0.0-beta.4 — an icon of its own

Five bars on one baseline, high-low-lowest-low-high. As a chart it reads as cell voltages, as a silhouette the tops trace an M — no borrowed logo.

The sidebar icon comes from a custom icon set in its own 0.24 kB bundle, loaded on every page because the sidebar draws its entry before anyone opens the panel. Missing file falls back to mdi:home-battery.

assets/make_brand_icons.py renders the HACS brand icons from the same geometry — icon.png at 256 and icon@2x.png at 512 — so the sidebar path and the PNGs cannot drift apart. It needs nothing installed.

A full Home Assistant restart, not a reload. Browsers cache the icon bundle, so a hard refresh may be needed for the sidebar to pick it up.
