 * FROM FIRE TO ORBIT — Reboot Phase 21
 * css/vab3d.css  ·  The Next-Gen 3D VAB — glassmorphism catalog + telemetry deck
 *
 * Everything here skins the existing #preview-modal (the "Assembly Bay") which
 * used to be a passive spin-and-look viewer. Phase 21 turns it into the primary
 * fluid, aerospace-grade construction surface — the interaction logic lives in
 * app.js (findSnapCandidates / ghost-part fly-in / magnetic snap), this file is
 * purely the "make it feel like Tony Stark's workshop" skin.
