/* ============================================================
   ASCENDANT — PROGRESSION-COACHING SURFACES (production port of the
   Claude Design "Progression Coaching" package, 1:1).
   Loads AFTER system.css + skilltrain.css (reuses their tokens + the
   prog-offer / prog-settled / done-tiles vocabulary). All colour via
   CSS variables so a World re-skin flows.
   Surfaces: A offer · B session-end tenure · C manual level-up · D ladder.
   (`.forge` from the design is namespaced `.cforge` here — the routine
   builder already owns a `.forge` class in system.css.)
