v0.2.1

Fixed

• Brand logo rendering for wide wordmarks (ROSA3D). The logo widget was a
  52×52 px square — ROSA3D's 334×94 wordmark was squished to ~15 px tall.
  load_brand_pixmap now accepts a separate max_w bound; the logo widget is
  160×52 px (left-aligned), so ROSA3D renders at ~160×45 px while square logos
  (Polymaker, Prusament) are unaffected.
