QR Code Generator v1.0.2 — Dark UI + font, glyph & color pickers

QR Code Generator v1.0.2

A big polish release: a dark UI, richer center-graphic tools, a color picker with
contrast checking, and a preview that keeps up with you.

New

• Dark theme throughout, with a preview background toggle (white ⇄ dark) so you
  can check how a code reads on light or dark surfaces.
• Choose font & glyph in one dialog — pick a font (installed by name via System
  fonts…, or any file via Browse…), then browse the font's glyphs in a paged,
  searchable grid and click to build the character string.
• Color picker on every color field: a curated palette plus hex and R/G/B
  inputs, with a WCAG contrast hint that warns before you make an unscannable code.
• Glyph background color, including transparent ("none") so the glyph can sit
  directly on the code.
• Batch → ZIP now applies every Single-tab setting — colors, error correction, and the
  center graphic — with a read-only summary of what will be used.
• Two-column URL-builder form with an optional "wide" flag per parameter.
• Live preview that regenerates automatically as you edit (on leaving a field or
  confirming a picker); invalid input keeps the last good preview instead of interrupting.

Fixed

• Switching fonts could show a previously loaded font's glyphs (a WPF font-cache issue) —
  the exact file is now loaded first, fixing the picker, preview, and output together.
• The glyph-color contrast rating now measures against the glyph background (or the
  light modules when transparent), instead of the dark modules — so low-contrast glyphs are
  correctly flagged.
