HADS Inside the Picker, Faster Dashboards & Cleaner Connectors

🚀 Drag & Drop Card Update

This release focuses on faster startup, a much better card picker, deeper HADS integration, and several important bug fixes before rollout.

⚡ Startup Optimizations

• Improved first-time initialization for dashboards using DDC cards.
• Reduced unnecessary work during the first render.
• Optimized layout, card, and dashboard-state loading.
• Improved performance for heavier dashboards and full DDC layouts.

🛒 HADS Integration in the Card Picker

• Added a dedicated HADS tab in the card picker.
• Browse the HADS catalog directly inside Drag & Drop Card.
• Listings now support images, pricing/status, details, and marketplace actions.
• Added Download & import for owned cards and free listings.
• Added Buy for paid listings the user does not own.
• HADS cards can now be imported directly into the dashboard without manual JSON import.
• Owned cards only appears when the user is actually connected to HADS.
• Create user now opens the correct HADS signup page.
• Added safer fallback behavior when the live HADS API is not available yet.

📦 Import & Placement

• HADS imports now land inside the selected DDC area when the user drag-selects an area before opening the picker.
• Cards added through the normal Add card button now appear in the top-left corner.
• Default size for newly added cards is now 350px x 350px.
• This applies to regular cards and HADS imports when no area is selected.

🔌 Connector Improvements

• Connector endpoints now stop at the card edge instead of disappearing behind the card.
• Connector lines now stop before the arrowhead, so the stroke no longer runs through the arrow.
• Improved connector rendering for energy-flow and diagram-style dashboards.
• Updated layer-order helper text to clarify that lines can stack against both cards and other lines.

🐛 Bug Fixes

• Fixed deleted screensaver entities coming back as [object Object].
• Fixed HADS Owned cards showing cached/random cards when the user was not connected.
• Fixed imported HADS cards not respecting the selected DDC placement area.
• Fixed connector arrowheads and line rendering edge cases.
• Updated the bundled dist build.
