d2 emits SVG natively; its PNG path wants a ~150 MB headless-Chromium download and prompts interactively, so every PNG here was produced by an out-of-band magick step. There is no Chromium on this system. Dropping PNG removes the dependency rather than trading one format for another, and cuts docs/diagrams/ from 17 MB to 3.3 MB. SVG renders in Gitea and in clide (`clide draw --file <path>`, which takes .d2 source directly), and diffs as text. One PNG is kept on purpose: design/star-map-concentric.png has no .d2 source. Also renders the 7 star-map .d2 files for the first time. star-map-plan.md listed their renders as a deliverable in March and the step never ran; the new `make check-diagrams` is what surfaced it. New: docs/diagrams/data-flow/wiki-generator-flow.d2 — which way the arrows point for any file under wiki/. Every edge was read in the tool's own source rather than inferred. It records the trap that keeps costing us: scaffold_bodies.py writes a body page once and never overwrites it, and the generator then reads that frontmatter directly — so a hand-edit there is not reverted, it is obeyed, and silently changes world generation. Two rendering traps found the expensive way and now written down: - A d2 `|md` block becomes an SVG <foreignObject>. ImageMagick and flutter_svg both silently drop it, so the legend was in the file and invisible in every viewer except a browser. Plain labels render as real <text> everywhere. - Container boxes fight the layout engine. Grouping nodes whose flow-depths differ forces long edge routes; this diagram went from an unreadable 2.4:1 sprawl to a legible 0.75:1 by deleting five containers and changing nothing else. Colour classes carry the grouping instead. make diagrams / make check-diagrams render and gate. Repo-specific rules in .claude/rules/diagrams.md; d2 syntax and the traps live in the user-scope d2-diagram skill, whose PNG default was flipped to SVG to match.
