   MYWU Labs™ lockup — one piece of finished artwork per theme

   The supplied logo is already a complete lockup: the interlocked MYWU
   monogram, the wordmark (MYWU … LS), the cat, and the μ / ✦ / ruler / brain /
   RNA / Σ glyph rail along the bottom rule. So the old assembly of "mark image
   + live MYWU / Labs™ text" is gone — there is nothing left to set in type, and
   no stack of webfonts could match the artwork's letterforms anyway.

   Two files, same geometry, one per theme. The light artwork's navy (#142c4a)
   has ~75% of its ink below L45, so it disappears on #0c0f14; the dark artwork
   is that drawing with only the navy strokes lifted along a slate→periwinkle
   ramp, which keeps the monogram legible while the gold rail stays identical.
   The light master is hand-authored; the dark sibling is generated from it by
   scripts/make-brand-icons.py, so a rebrand replaces one file.
