Turn every working session into a clean, dated development journal, automatically. Use when writing a development session log — it captures the session into a self-contained, dependency-free HTML page and updates a running index. Creates a new sequenced file per call so it never overwrites past logs, adapting to any repo via config.

# Devlog Workflow
Capture a development session as a dated HTML log.
## Gather the session
Summarize what happened this session into the configured sections (default: Summary, Changes, Decisions, Next). Each section's content must be a **fragment of valid HTML** (e.g. `<p>...</p>`, `<ul><li>...</li></ul>`).
Build a JSON object:
```json
{
"title": "Short session title",
"sections": [
{ "heading": "Summary", "html": "<p>...</p>" },
{ "heading": "Changes", "html": "<ul><li>...</li></ul>" }
]
}
```
## Render
Pipe the JSON into the helper with today's date:
```bash
echo "$JSON" | node "${CLAUDE_PLUGIN_ROOT}/scripts/devlog-render.mjs" --date <today>
```
The helper writes `<devlog.dir>/YYYY-MM-DD.html` (sequencing `-2`, `-3` on repeat calls the same day — it never overwrites) and rebuilds `index.html`.
## Rules
- Use today's real date (never guess).
- Repeat calls the same day create new sequenced files; do not overwrite prior logs.
- Keep HTML fragments self-contained — no external scripts or stylesheets.
