+-- TotemBar - minimap.lua
+-- Hand-rolled minimap button (no LibDBIcon on 1.12). Orbits the minimap at a
+-- saved angle, drag-repositions (angle persisted), left-click opens the
+-- options panel, right-click toggles the bar. pfUI-safe: parent = Minimap,
+-- name contains "Minimap", FrameStrata HIGH + level 9 (MEDIUM hides under
+-- pfUI). /tb options is the guaranteed access path if pfUI collects/hides
+-- the button. WoW-API file (parse-checked only).
