feat(packages): ludic.character - a third-person walking body: walk and run with their acceleration, a jump and gravity, a step within CHAR_STEP taken and a slope above it measured over a fixed probe, wading that shelves into a swim, the dive and the breath, sitting, one safe put-down spot, holds by reason, being carried, and the orbit camera with first-person eyes; ground, body and stick through ports; landed, jumped, footfall, too steep, the water's facts

+# ludic.character - one body under a player's stick: the game says where the ground, the water and
+# the colliders are and what the stick asks; the package moves the body and its camera and says
+# what happened. It never draws: the game poses a figure and points its camera from the queries.
