   Design B — "soundings" remapped to [data-design="b"]
   Adaven Plumbing Inc. · Las Vegas NV
   Calypso logbooks × Braun marine instruments — chart-paper cream,
   sonar cyan, anodized brass bezels. Instrument-calibrated register.
   --design-b-primary exposed per contract.

   CHROME-KIT SCOPE GUARD:
   EVERY selector starts with [data-design="b"].
   img/svg resets scoped to [data-design="b"].dq-design to avoid
   leaking onto .mf-forge__scene (fixes modal_smoke_error).
   ZERO bare element/global rules for position/z-index/display/
   visibility/pointer-events/overflow.
