2026.8.3-b2

Beta iteration on top of 2026.8.3-b1.

Fixed since b1

• A sun-position card (home hidden, only the sun chip) no longer shows an empty home ring. The sun chip has no leader to the home, so it no longer keeps the home anchor: such a card now shows just the sun and the location (#310). Thanks @ferreto1978.

Everything from b1 is included: reversed grid import/export icons (#352), one shared configurable flow reference with the new Max expected power setting (#351), the optional sun-position readout on the sun chip (#310), and the grid bead outline.
