+Opened 2026-10-01 as drafts from per-PR branches cut from upstream `60efdef`
+(code only; `docs/hails-additions` stays in the fork). #29 (G) is stacked on
+#28 (F); in the upstream branches the customiser-overlap hunks of `install.py`
+live in G, and each branch has its own equivalence pairs (F: maps main→F;
+G: character/environment/maps from main and from F). Bodies: `.claude/pr-drafts/`.
