How it plays. Three walled districts, 8×8, 9×9, 10×10.
A beacon lights its own cell and every open cell in the four straight lines from it,
until a wall (🧱) stops the light. Light travels through other beacons.
When every street is lit the level ends — its score is
round(1000 × fewest-possible-beacons ÷ your beacons) (max 1000 per level,
3000 total). The fewest-possible count is computed exactly and revealed when the level ends.
