  Each SVG is 39 mm x 39 mm (viewBox 0 0 39 39 = mm). Disc centre = (19.5, 19.5).
  Layer "ENGRAVE": black filled shapes = mark. Everything else = leave bare copper.
  All text is converted to outlines (no fonts needed, no emoji glyphs).
  Layer "CUT GUIDE - DO NOT ENGRAVE" (red): 39 mm disc outline, dashed 37 mm circle = 1 mm rim margin,
  centre cross, and on the back the 24 mm QR quiet-zone square (dashed). Alignment only - do not engrave or cut.
  Nothing is marked outside r = 18.5 mm (1 mm rim margin kept bare).

MACHINE / PROCESS
  - Fiber laser, solid copper.
  - BACK (QR): DARKEN / BLACK-MARK the modules - a surface colour mark, NOT a deep engrave.
    Keep the QR area flat and high-contrast: dark modules on bright, clean copper.
    Fill the modules completely and evenly (fine hatch, cross-hatch recommended); keep module
    edges crisp - no bleed into neighbouring light modules. Light modules and the quiet zone
    must stay bright, unmarked copper (do not frost/anneal them).
    QR: version 2, error correction M, 25 x 25 modules, module = 0.727 mm,
    symbol 18.18 mm square, 24.0 mm including the 4-module quiet zone. Encodes https://huxleydollar.com
    Rim text stays >= 0.6 mm outside the quiet zone.
  - FRONT (feather + legends): dark mark, or a light engrave + dark mark - shop's choice.
    Laser-friendly by construction: every mark >= 0.30 mm wide and every gap >= 0.30 mm
    (geometry passed through a 0.31 mm opening/closing filter and checked).
    Feather: copper barb slits 0.34 mm, black between slits >= 0.45 mm, copper rachis 0.34-0.46 mm,
    quill 0.54-0.88 mm. Rim ring 0.45 mm, beads 0.5 mm with ~0.5 mm gaps.
  - Polish/clean both faces before marking. After marking, clean off residue and
    CLEAR-COAT (lacquer / clear enamel) both faces so the copper does not tarnish and kill QR contrast.
  - Please test-scan the QR with a phone on the first piece before running the batch.
