+Description: >
+  The Welcome showcase rebuilt from pod graphs. Apart from the Panda arm, everything in the scene is a
+  procedural pod graph rather than an imported GLB: the room and its three paintings, the prop tray with
+  its cube, cone, sphere and cylinder, the Lucky Robots logo, the four steel balls and the marble run
+  itself. The run is 29 pieces made from nine parametric piece graphs in Assets/MarbleRun (straight, turn,
+  wave, catch, reducer, bowl, rails, end cup and pole), each textured with a wood grain that follows the
+  piece; the tray and the logo use the same wood. As in the original, a C# script drives the Panda through
+  the MG_Panda_Pod_IK motion graph, picking each ball out of the end cup and dropping it back at the top,
+  so the run keeps going on its own.
+  Two scenes. Welcome is the start scene. It ships the convex collision hulls for every track piece
+  (Assets/Physics/ConvexHulls), so Play needs no bake; in testing, 150 s of Play gave 23 laps with no
+  ball stuck. Welcome-Generated is an experiment: the whole run is one pod graph
+  (MarbleRun/generated_run), whose Run / Seed parameter lays out a different run for every seed, with
+  every piece standing on a pole. Seed -1, as shipped, rebuilds the Welcome layout. Its piece bodies are
+  made when the graph cooks, so their hulls cannot be stored in the scene. The first Play on each machine
+  therefore bakes them with CoACD (about 46 s for the shipped seed on the machine it was built on), and
+  later Plays load them from the project's Cache folder. Changing the seed bakes only the pieces whose
+  shape is new.
+  The marble-run graphs are generated by the pod repository's marble-run tools
+  (tools/make_marble_run.py, tools/install_marble_run.py). Change a piece there and re-install it;
+  don't edit the .hpodgraph files by hand.
+  NOT INCLUDED: the bake and MuJoCo model caches (Cache/), compiled scripts (the C# project builds on
+  first open from Assets/Scripts/Source and the scene scripts), and per-user editor files.
