Three fixes for usable world objects, found play-testing multiplayer_world (Elddim). The first two also apply to the single-player campaign.

Doors open only within reach. A door click ran OpenDoorNear straight from the click handler, which opened the closed door nearest the click from any distance; the template's DoorUseRange was read but never checked.

• A click now queues a walk-up-and-open like chests and levers (_pendingDoorUse); the acting character walks to the click and the door opens on arrival.
• In range = XZ distance from the hinge ≤ the leaf's footprint radius + [aspect] use_range (default 1.5), same floor (within 3 u). The footprint term is needed because a closed door's nav obstacle keeps the walker about one leaf length from the hinge (UseRange.DoorInRange, unit-tested).
• The use_toggle "It won't budge." line now shows on arrival rather than on the click.

Skinned props drawn in their rest pose. The switch family's clips (a_i_glb_switch-06-open/close.prs, also lever_glb_01/02/03) hold the root bone at (0,-0.183,-1.0) for the whole clip while the bind pose has it at z 0. DS1 draws the prop in that animated pose and the maps are placed for it; SiegeFX drew static skinned props at bind, so the teleporter call button (lever_glb_06) floated ~1 u over its platform in all 9 MP towns, and SP wall switches (dm_r8a, cr_r1) stood ~1 u off their walls.

• AnimationRuntime.TryRootRestOffset returns the root's skin matrix only when the clip holds the root still and away from bind; a moving root (e.g. statue_cav_rise_01) is left alone.
• PropRestPose picks the resting clip (chore_default, else chore_open/close; also the anim_files:00 = shorthand). The static prop path applies restOffset * world before scale_multiplier, so the offset itself is not scaled (other towns' buttons use scale 2 and only sit right that way). Cached per template+mesh, logged once as [rest-pose].
• Sweep of Logic.dsres: applies to lever_glb_01/02/03/06/06_message (-1 Z) and lever_gob_01 (+0.757 Z, not checked against geometry); a few others are ≤ 0.007.

Town teleporters ride. Every MP town's transport stone is an elevator_instant_4s_1c gizmo driving two cars between two shafts: the town car and its twin in new_hub. A press raises both cars, swaps them between the shafts and sinks them, so the riders step off in the hub; the 8 towns pair with new_hub's 8 gizmos (other_elevator), 9 more pairs link regions point to point; actioninfo is a mood name here.

• ElevatorStore only read connect_node / connect_node_levelN; it now parses the connect_node_location1/2 form into ElevatorDef.Instant, with InstantElevatorPlan as the skrit's state machine in data.
• new_hub has no stitch_helper, so no world position: it streams in when a teleporter is pressed and WorldLayout places it as an island at a pinned, deterministic offset. The press is queued and handled from TickElevators.
• The ride moves both cars, carries riders through the swap, applies the moods, re-bakes nav, and moves objects placed on a car node with it (the button rides its car). This applies to all lifts.
• Trigger change: rows mixing receive_world_message with a volume condition in boundary mode wait_for_every_message / wait_for_first_message now treat the volume as a gate on the message (the editor labels these "message checker"). Before, stepping onto the platform launched the teleporter by itself, and arriving launched it straight back. World.dsmap has ~30 rows of this form; they now need their message too. Receipts pass, but those SP spots were not played through.

Checks

• dotnet build SiegeFX.sln -c Release -warnaserror: clean. dotnet test: 147/147, with new UseRangeTests, PropRestPoseTests, InstantElevatorTests (data-free).
• tools/receipts.sh: all PASS; parity ledger better (template-fields 397 -> 400), no regressions.
• Runtime runs on multiplayer_world town_center in a co-op development branch carrying these commits (checked from logs and engine screenshots, not a full play-through): doors open once the hero reaches them ([door] … reached: actor 2.1u from the hinge), lever_glb_06 now sits at y 6.6 on the 6.55 platform (was ~7.6), and a scripted press rides town → hub → town with the rider carried both ways.

RenderHost becomes partial here as in #36 (same one-line change).
