1.2.0

Added

• Power / Energy Toggle — Configure both a power entity (entity) and an energy entity (entity_energy) per panel. A slide toggle in the top-right corner of the card switches the entire view between W and kWh readings.
• Per-Panel Rotation — Each panel can now be individually rotated (-180° to 180°) to match its physical orientation on your roof. Configurable via a slider in the visual editor.
• Canvas Rotation — Rotate the entire panel grid (-180° to 180°) with a single setting, useful when your array is installed at an angle relative to north.
• Background Image — Set an overhead/satellite image as the card background. Adjustable opacity lets you keep panels readable while showing roof layout.
• Card Picker Registration — The card now appears in Home Assistant's "Add Card" dialog, making it easier to discover and add to dashboards.

Changed

• Auto-Sizing Canvas — The card container now dynamically sizes to fit the placed panels with minimal padding, eliminating unnecessary scrollbars in dashboard view. The editor preview retains a large workspace for easy panel placement.
• Rotation Slider — The per-panel rotation field in the editor is now a styled range slider (step 5°) instead of a plain text input, matching the canvas rotation control.
