Logo — vector lockup (for approval, task 141)

Top: the original raster. Bottom: the traced SVG rendered back at the same size.

Source: brand/artwork/logo/embeddedera-lockup.svg (35 kB, 21 paths). Record: logo/record.yml. If it passes, the site's raster logos get replaced by this file and the brand README's logo table points here. If anything looks off, say which letter or edge.

v2 — constructed vector (APPROVED by Angel 2026-10-23)

Site switch built in worktree ~/embeddedera-site-logov2 — LIVE 2026-10-23 (PR #8, main @3569db9). Comparison: logo-v1-vs-v2.png; site preview: site-logo-v2-preview.png. In use in the KiCad template since 2026-10-16 (owner: "fix the logo with our new one"): title-block wordmark and the silkscreen logo footprints. The site and favicon still carry v1.

Rebuilt from measured geometry in VectorCraft, not traced: the mark is 3-fold symmetric on a 24/28 grid (stroke 24, gap 28, pitch 52; centre ring thickened from about 21 to 24 to match), and the letters use stroke 15, concentric corners R18/R3, a 5.5 stencil gap and a 30 letter gap. Every curve join is tangent: fillet.py adds an R3 concave fillet where two arcs collided (M notch, B and R waists, which the original also had as sharp kinks); owner asked 2026-10-12 that "everything needs to be tangent". Then smooth.py makes all 40 round corners curvature-continuous (G2): two mirror cubics per corner, zero curvature at the straight edge, same visual depth as the R18 circle, extent 1.6R (less where edges are short). Figma corner smoothing (figma-squircle math) was tried first and rejected: its Bezier-to-arc join still stepped up to 83% in curvature. Still G1 only: the M dip and the B/R waists (concave R3 fillets). Each file is one compound path, about 5 KB. Files: NAS share EmbeddedEra/design/logo-v2/ (server ~/design/logo-v2/, Mac /Volumes/EmbeddedEra/design/logo-v2/; ./make.sh rebuilds) ({svg,pdf,eps,png} × lockup/mark/wordmark × black/white/copper; construct.py + mark.json regenerate everything). Proof page with side-by-side and photo before/after: https://claude.ai/artifact/WtcBQeVEggobz7QSgvM7pe. On approval: copy into brand/artwork/logo/v2/, replace the site's logo.svg/logo-white.svg/favicon via the dev preview, update the brand README logo table.

Stamp version, 1.8 × 0.6 in (2026-11-02)

Side-by-side version (mark + wordmark) built from v2 for a stamp order: logo/stamp/embeddedera-stamp-1.8x0.6in.{pdf,svg,eps} + 1200 dpi PNG. Mark 0.45 × 0.52 in, wordmark 1.17 in wide; 0.04 in margin.
