Add subscription status colors: green (paid active), blue (trial active),
red (paid expired), orange (trial expired). Extract NODE_COLORS constant
as single source of truth. Add SubscriptionStatus union type. Show status
badge in user detail panel. Add i18n for all 4 locales.
Portal to document.body escapes main's contain:content which broke
fixed positioning (container had height:0 and was clipped to main).
Visual fixes for 662+ node graphs:
- labels only on large nodes (threshold 6→14, density 0.5→0.12)
- leaf nodes 5px, referrers 10px, campaigns 16px
- edge opacity reduced to prevent white starburst
- default edge color opacity lowered
- fix top offset breakpoint: sm:top-14 → lg:top-14 to match AppShell
header visibility (mobile header is lg:hidden with h-16)
- add gravity to FA2 layout to prevent disconnected nodes from flying
to extreme positions, making auto-rescale shrink everything to dots
- clamp outlier node positions after FA2 finishes (3σ threshold)
- add ResizeObserver to sync sigma canvas with container size changes
- call sigma.resize() before camera reset after FA2
- increase node sizes: user min 8→12, max 40→50, campaign 18→24
- reduce FA2 duration 5s→3s and slowDown 5→2 for tighter layout
- Switch to CSS Grid layout for reliable content area height
- Use inferSettings() for ForceAtlas2 auto-tuning based on graph structure
- Enable linLogMode and adjustSizes for better node clustering
- Fit camera after layout settles with animatedReset
- Increase node sizes for better visibility (MIN 8, MAX 40)
- Center controls at bottom, fix overlay positions
