/* ASi Imperium — Scope & Estimate
   Two columns on desktop, stacked on a phone. The result card sticks so the range
   stays in view while the answers change; on a phone a compact bar carries it instead.
   Performance rules (AGENTS.md §6a): no backdrop-filter, transitions on named
   properties only, the one animated bar moves by transform. */
