feat(markdown-html): add v2.10.0 foundation — orchestrator + design-system
Operationalizes Shihipar's "Claude Code HTML output" essay (Medium, 2026):
markdown collapses past ~100 lines for agent-generated artifacts; HTML
restores density, clarity, shareability, and lightweight interaction.

This foundation PR ships 2 of 5 planned skills:

- markdown-html-orchestrator (context: fork): deterministic doctype
  classifier scoring filename hints + content signals across DOCUMENT /
  REVIEW / SLIDES; silent-routes above two-signal threshold; refuses
  inputs < 100 lines per Shihipar; refuses without design-system
  onboarding. 3 stdlib tools: doctype_classifier.py, route_explainer.py
  (the never-silently-chain enforcer + onboarding gate), and
  output_path_resolver.py (kebab slug + collision suffix).

- design-system: one-time onboarding wizard (10 questions for brand
  primary/accent HEX + heading + body Google Fonts + editorial/technical/
  minimal/playful style + default output dir + syntax theme + TOC
  behavior + optional logo/company). WCAG-AA-validated 12 CSS custom
  properties derived in HSL space; refuses to save if body-text or link
  contrast fails 4.5:1, or if the output dir is unwritable. Pattern
  lifted from research-ops/skills/clinical-research/scripts/ (onboard.py
  + config_loader.py shape) and marketing/landing/scripts/
  (brand_palette_validator.py WCAG + HSL math). Precedence: project >
  global > defaults; MARKDOWN_HTML_NO_CONFIG=1 bypasses.

Plus cs-markdown-html-orchestrator agent, 3 slash commands
(/cs:markdown-html router, /cs:grill-markdown-html 5-question grill,
/cs:design-system onboarding surface), 6 reference docs each citing 5-7
authoritative sources (Tufte, Shihipar, Bret Victor, Maggie Appleton,
Bartosz Ciechanowski, Amelia Wattenberger; WCAG 2.2, Ellen Lupton,
Adobe Spectrum, Sara Soueidan, Material Design 3), 1 JSON schema asset,
domain README + CLAUDE.md.

Converter sub-skills (md-document, md-review, md-slides) land in v2.10.1
follow-up PRs. All three will import design-system/scripts/config_loader.py
for shared brand tokens.

Repo-level updates: scripts/sync-codex-skills.py SKILL_DOMAINS adds
markdown-html → documentation category; .claude-plugin/marketplace.json
adds markdown-html-skills plugin entry (63 → 64 plugins, 16 → 17
domains); root CLAUDE.md gets nav-map row, structure-tree entry, and
v2.10.0 release-notes block.

Validation:
- check_plugin_json.py → OK
- sync-codex-skills.py --dry-run → 2 new symlinks, total 338 → 340
- skill_description_validator.py → PASS on both SKILL.md files
- skill_review_checklist_runner.py → 5/6 PASS (under-100-lines advisory
  fires; same as research-ops orchestrator)
- All 6 Python tools smoke-tested with --help and --sample
- End-to-end onboarding round-trip works (--defaults, --set, --reset)
- WCAG-fail hard refusal fires correctly on impossible color combos
- Classifier on the repo's own CLAUDE.md correctly returns
  needs-clarification (15 vs 13 — document signals tie with slides
  signals because of multiple --- HRs); orchestrator asks rather than
  silently chains.

Distinct from Anthropic's official Playground plugin (interactive
prompt-tuning controls with sliders/knobs/prompt-copy-back) and from
marketing/landing/ (landing-page generator from scratch).

description argument-hint
Run the one-time markdown-html design-system onboarding wizard. Captures brand primary/accent (HEX) + heading/body Google Fonts + design style (editorial/technical/minimal/playful) + default output directory + syntax theme + TOC behavior + optional logo/company. WCAG-AA validates body-text contrast; refuses if it fails. Stores at ~/.config/markdown-html/design-system.json (or project-scoped with --scope project). Every converter reads this config via config_loader.py before rendering. [--defaults | --show | --reset | --set key=value | --scope global|project]

/cs:design-system — Markdown-HTML design-system onboarding

Run the design-system wizard:

python3 markdown-html/skills/design-system/scripts/onboard.py $ARGUMENTS

Modes

Flag Behavior
(no flag) Interactive — walks 10 questions one at a time. Default.
--defaults Zero-touch: writes built-in defaults (#0A1628 navy + #00D4AA teal + Inter + technical + sticky TOC + ./markdown-html-out/) without prompting. Useful for CI or first-test.
--set key=value Non-interactive override (repeatable). Dotted keys supported: brand.primary=#FF6B35, typography.heading_font=Lora, design_style=editorial.
--show Print the 10 questions + the current effective config (project > global > defaults).
--reset Delete the saved config at the chosen scope.
--scope project Save to ./.markdown-html/design-system.json (per-repo override) instead of global ~/.config/markdown-html/design-system.json.

The 10 questions

  1. Default output directory (path; must be writable)
  2. Brand primary HEX
  3. Brand accent HEX (optional; auto-derives if blank)
  4. Heading Google Font (12 safe defaults)
  5. Body Google Font
  6. Design style: editorial / technical / minimal / playful
  7. Syntax-highlighting theme: light / dark / auto
  8. TOC behavior: sticky-sidebar / collapsible-top / inline / none
  9. Company / project name (optional, shows in footer)
  10. Logo URL (optional, base64-embedded at render time)

Hard refusals

  • default_output_dir empty or unwritable → exit 3. Pick a path you control.
  • WCAG AA body-text contrast fails (< 4.5:1) → exit 4. Pick a darker primary, blank brand.bg/brand.text to let derivation pick a passing pair, or override brand.text explicitly.
  • WCAG link contrast walked iteratively; falls back to a passing color if accent on bg can't reach 4.5:1.

After onboarding

Inspect the effective config:

python3 markdown-html/skills/design-system/scripts/config_loader.py --show
python3 markdown-html/skills/design-system/scripts/config_loader.py --status

Then convert markdown via /cs:markdown-html <path>.md.

Bypass

MARKDOWN_HTML_NO_CONFIG=1 skips saved config and returns DEFAULTS only. Useful for headless CI, ephemeral test containers, and evaluator loops. Never set it silently for an interactive user.
