Increased inactive heaven bead gap from 3pt to 8pt for better visual
balance with earth beads. Now positioned at 14pt from top vs
reckoning bar at 20pt, giving 6pt clearance.
This provides more proportional spacing compared to earth beads
while keeping heaven beads clearly above the reckoning bar.
Updated all example images to reflect the improved positioning.

My previous attempt to match earth bead gaps exactly resulted in
inactive heaven beads appearing below the reckoning bar at 27pt
while the bar is at 20pt.
Fixed by:
- Positioning inactive heaven beads at bead-size/2 + 3pt = 9pt from top
- This places them clearly above the reckoning bar (at 20pt)
- Removed unused inactive-bead-gap variable
- Active heaven beads remain just above the bar as intended

The 'Check My Solution' and 'End Game' buttons were hidden because
they were inside the .sorting-controls div, which gets hidden when
the game starts.
Solution:
- Move action buttons outside .sorting-controls into new .sorting-game-actions div
- Show/hide the entire .sorting-game-actions container instead of individual buttons
- Add CSS styling for the new container
- Buttons now remain visible throughout sorting gameplay

The previous fix used a fixed 5pt gap for heaven beads while earth beads
used a calculated gap of (bead-size + bead-spacing) + 5pt = 21pt.
This fix:
- Adds inactive-bead-gap variable for consistency
- Makes inactive heaven beads use same gap calculation as earth beads
- Now both heaven and earth inactive beads have visually equal spacing
- Updated all example images to show the corrected equal spacing

Fix heaven bead positioning issue where inactive heaven beads appeared
too close to the reckoning bar. Now inactive heaven beads use the same
5pt gap as inactive earth beads for visual consistency.
Changes:
- Inactive heaven beads: moved from 5pt+bead-size/2 to bead-size/2+5pt gap
- Active heaven beads: fine-tuned to heaven-earth-gap-bead-size/2-1pt
- Updated example images to reflect corrected positioning
