/* ===== TOOL COMPONENT (2026-07-04 reference: fire-calculator) =====
   The reusable, token-driven vocabulary that the 89-tool fleet migrates onto.
   Design brief: Tufte density + Pico form polish + icon/label restraint, on the
   existing dark financial-terminal identity. Every value is a token — no hex.
   Reuses existing containers rather than forking them:
     .tool-layout / .tool-inputs  (grid + sticky sidebar + global focus ring)
     .tool-assumptions            (the "what this assumes" disclosure)
     .tool-actions                (share / export button row)
     .tool-results-sticky         (mobile pinned result bar)
   Everything below is additive and generic — no fire-specific names.
