AKUNUR BOARD DESIGN NOTES — TRIANGLE SECTOR BUILD

This build keeps the successful alternating ring shading and reworks the sector
guides to follow the six long board edges rather than the six corners.

Key change
- The six sectors are now treated as equilateral triangles that meet at the
  Still Point and have their base along one outer side of the board.

Element placement
- Upper-left edge: Fire
- Top edge: Snow
- Upper-right edge: Wind
- Lower-right edge: Rain
- Bottom edge: Sand
- Lower-left edge: Rock

Opposites remain
- Wind ↔ Rock
- Rain ↔ Fire
- Sand ↔ Snow

Visual treatment
- Alternating ring shading remains the primary cue.
- Each triangular sector gets a very faint tonal wash.
- Subtle divider rays run from the Still Point towards the six board corners.
- Element symbols and labels are placed outside the board and aligned with the
  corresponding long edge.

Mental rule under test
- Same ring → opposite triangle → same offset within the triangle.
