The logo overlay rendered invisible. Inside a viewBox-scaled foreignObject a
fixed px padding (var(--space-1)) equals that many *modules*, overflowing the
cleared centre and collapsing the content box; inline-size/block-size also
don't size an <svg> element. Fix: proportional inline padding + physical
width/height. The logo now renders and still decodes at ECC H. Dropped the
now-orphan --qr-code-overlay-padding token + regenerated base.css.
Demo: content presets (URL / vCard / WiFi / unicode) prove the encoder takes
any UTF-8 string, not just URLs (each verified decoding via jsQR); logo on by
default; quiet-zone chips fixed to canonical [4, 8, 16] (was [2, …], below the
spec's 4-module minimum). README documents the quiet zone as modules, not
pixels — the canonical unit; for px layout spacing, pad the container in CSS.

Own QR encoder in $libs/qr (ISO/IEC 18004: segment analysis →
Reed-Solomon over GF(256) → matrix layout → 8-mask penalty selection),
no npm dependency. Eidos <QrCode> renders the module matrix as one SVG
path with square/rounded/dots cell shapes; function patterns stay square
(via the encoder's `reserved` mask) so every shape scans. Optional logo
clears the centre + auto-boosts ECC to H. <QrCode.DownloadTrigger>
exports PNG/SVG, baking resolved colours into the clone first (a
serialized SVG loses the document's CSS custom properties). Fixed-tone
default colours for scannability; themeable via color/background.
morfo qr-code (scope: eidos; parts Provider/Pattern/Overlay/
DownloadTrigger) + 'path' added to MorfoElement; recipe with 11
--qr-code-* tokens; canonical demo + nav entry. 11 encoder unit tests;
verified end-to-end via jsQR round-trip + browser.
