BV engineering-review mesh source notices

BV derives from the six saved BU native files.  Both visible metal lamp faces
are rebuilt as single-solid, 0.4 mm decorative nameplates with buried 0.1 mm
bridge tabs.  The left square pinwheel has clean flush optic joins.  The right
light guide is a pure hexagonal prism; the inherited circular optical mounting
disk and the visible-depth circular upper-housing pocket are removed.  The
right upper seat and adhesive remain six-point-star geometry.

This non-commercial review contains tessellated display assets, not fabrication
files or a manufacturing release. Native CAD, KiCad, STEP and Gerber files are
not included. The buried-bridge/inlay process, adhesion, optical uniformity,
tolerances, supplier DFM and real assembly remain unapproved.
