   CRIMSON DOMINION — UNIT CHASSIS KIT   (internal kit key `legion`)

   ----------------------------------------------------------------------------

   STRENGTH. AUTHORITY. CONQUEST.



   The Dominion does not build elegant machines. It builds SLABS OF MOVING

   IRON: a base hull, then a second skin of applique armour bolted over the top

   of it, then whatever heat hardware is needed to survive running that much

   mass. Every chassis in this file is assembled from the same short vocabulary

   so the army reads as one manufacturer long before the player reads a colour:



     - broad tracked runs with a bolted skirt over the whole length, and the

       livery band always in the same place on that skirt;

     - blunt, bolted prows — chamfered, never raked to a point;

     - exposed vertical heat stacks with an open glowing bore;

     - riveted seams on every large flat plate;

     - almost no glass. Crews look through slits.



   It should look like it was built to be REPLACED, not maintained.



   Contract, copied from mdlLegionRhino(): +X is forward (the direction the

   unit shoots), +Y is up, Z is lateral, tracks/keel sit at y=0, and a builder

   returns {hull, tur, s, turH}. Unturreted units return tur:null and no turH.



   MATERIALS ARE LOAD-BEARING. TEAM_A/TEAM_B/TEAM_T are the only surfaces that

   take the faction's livery — two to five panels per model, never the whole

   hull. SERVO marks a surface as a LEG and the vertex stage swings it through

   the walk cycle, so it appears ONLY on the walkers (Goliath, TITAN,

   Constructor) and only below their hips. HOT and ENERGY are emissive and are

   rationed to heat bores, muzzle collars and equipment cores.



   Names are prefixed dom/mdlDom because this repo is one global scope.
