 ## Rock sprite atlas — re-uses the Grasslands tileset (already imported for the
-## decoration overlay). The three coords below were eyeballed from the
-## /tmp/rocks_review.png probe in the 2026-05-12 visual pass: two gray boulders
-## and one brown rock for variety.
+## decoration overlay). These coords pick standalone single-tile boulders from
+## the rock band (x=16..29, y=3 and y=5) — chosen because each has a clean
+## green margin on all four sides, so they read as separate small rocks rather
+## than chunks of a tiled cluster. The earlier (24,7)/(28,7)/(12,13) coords
+## were autotile interior pieces; replaced 2026-05-12 after the user flagged
+## the obvious tile-cluster artifacts on small rocks.
+##
+## Multi-tile cluster formations live at (22..23, 3..4) brown and (30..31, 3..4)
+## gray — those are reserved for the upcoming BigRock entity (2×2 boulder).
