v0.2.7

Fader card consistency

• Standardized height and spacing across single-channel, group, and multi-fixture faders (collapsed and expanded) so they all share the same visual shape
• Added a "GROUP" label above group names, and thin divider lines between adjacent channels
• Standalone single-channel and multi-fixture faders now show a card border, matching groups
• Gear/swatch/expand controls and per-channel link icons are properly centered within their footer area

Editing / interaction fixes

• Clicking a selected fixture in edit mode now deselects it
• Clicking "+" now exits edit mode
• Multi-channel sub-faders are disabled and their linked/unlinked state highlighted while editing
• Single-channel fixtures no longer overlap multi-channel fixtures in the layout
• New multi-channel fixture drafts auto-populate their first channel row; the channel-conflict toast now appears inside the affected draft card instead of a shared banner

Visual polish

• Color swatch stays visible (but inert) while editing, instead of dimming
• A multi-channel fixture's master fader is now labeled "MULTI"
