The README's "Browse the live gallery" link pointed at the raw HTML blob,
which GitHub renders as source code rather than the gallery. Add a Pages
deployment workflow that publishes skills/diagram-design/assets as a static
site, and point the README at the deployed gallery (closes#33).
Add CONTRIBUTING.md covering all validation gates and contribution
workflows, CODE_OF_CONDUCT.md (Contributor Covenant 2.1), GitHub issue
templates (bug/feature), and a pull request template; add a Contributing
section to the README.
Adds a draw.io import path to the skill. Points at a .drawio file and
produces an editorial diagram fitted to where it's going — not a
format conversion.
- scripts/drawio_extract.py: decodes all four containers draw.io writes
(raw XML, deflate+base64 payloads, PNG tEXt chunks, SVG content attrs),
flattens mxGraphModel into absolute-positioned nodes/edges, and reports
structural signals: hubs, containers, depth, cycles, collapsible leaf
groups, budget flags. Deterministic half — makes no design decisions.
- references/output-spec.md: the three dials. Nine size presets with
per-size-class type ramps and safe areas; faithful/balanced/simplified
detail levels with a fixed degrade ladder; engineer/mixed/executive
audience wording; fidelity ledger; CJK font fallback.
- references/import-drawio.md: the redraw procedure — extract, set dials,
pick type, build the semantic model, redraw on the grid. Includes the
draw.io palette/shape → semantic role mappings, multi-page handling,
edge cases, and anti-patterns.
- commands/import-drawio.md: /diagram-design:import slash command.
- SKILL.md: new §11 (import + output dials), taste-gate entries, §12 output.
- export.md: sizing section — scale factors and exact-pixel targets.
- assets/example-import-drawio.html: worked import of the checked-in
fixture at balanced/doc-inline, lint-clean.
- scripts/verify-drawio-import.py: drives the real extractor against the
fixture in all four containers and checks the references stay in sync.
faithful is the one documented exemption from the §7 complexity budget,
and it's conditional: zoned above 9 nodes, split above 24. The §6
connector rules never relax for imported content.
