Two cleanup passes + a shading-dome regression fix.
Editor structure pass
Three sections (PV, Weather, Battery) collapse into a single "PV installation" section that bundles the four install-level knobs without a HA Energy equivalent: peak kWp, inverter max kW, inverter-cutoff SoC %, optional solar-radiation override entity. The standalone UI section is gone, its only field (the auto-rotate camera toggle) moves into the map section renamed to "UI & map" so the camera animation knob sits next to the basemap chrome it shapes.
inverterCutoffSocPctHelp loses the trailing "Requires the battery SoC entity above to be configured" sentence in all 11 locales since the referenced field now lives in the HA Energy dashboard, not above.
i18n cleanup: drop lidarViewChipLabel + shadingDomeChipLabel (no rendered consumer left), drop mapSection / uiSection / pvSection / batterySection / weatherSection / weatherHint (replaced by uiAndMapSection + installationSection).
Comment cleanup across the whole repo
Strip See #N issue references from comments (helios-engine.ts, ws-timeout.ts, radiation.ts, pv.ts, lidar-view.ts, grid.ts, battery.ts, energy-prefs.ts, dashboard.ts, helios-card.ts, weather.ts). Strip v1.8.3 entity refonte version stamps. Rewrite state-field comments that referenced retired YAML entity keys to reference the HA Energy dashboard source they read from. Drop em-dashes from helios-card-css.ts. Drop "the legacy code used to produce" / "legacy raw 30-day path" framing. Drop the orphan "Battery-bank editor state machinery" comment header above the PV-arrays helpers.
Shading-dome HUD fade regression fix
ha-card.shading-dome-active rules inherited the home glow / silhouette / leader / chip fade list from the original mode-transition block but missed the .time-bar slide-out and the .overlay-top-left opacity-0 rule. So when the dome opened, the chips disappeared, but the timeline stayed visible and the camera-lock corner did not fade. Union the LiDAR + shading-dome selectors on those two rules so both modes share one animation set.
Forecast tooltip icon
The scrub tooltip's forecast row flips from mdi:chart-bell-curve-cumulative to mdi:crystal-ball, the distinction between today's observed kWh row and tomorrow's forecast kWh row reads at a glance.
Install
Alpha. Install via HACS with "Show beta versions" enabled. Same install footprint as alpha.10, the editor open-section identifier renamed from pv to installation so editor previews jump to the bundled section by default after the first refresh.
