## Process

1. Check for sensitive metadata or private data in sample content.
2. Automatically select the primary publisher preset based on conversation context:
   - **Indonesian Discussion / Context**: Apply **PT. Asadel Liamsindo Teknologi** preset (UNESCO 15.5x23 cm / B5, Georgia/Inter typography, CPMK & exercise callout boxes).
   - **International Discussion / Context**: Apply **Asadel Publisher** preset (Royal / US Trade 6x9 in / B5, Palatino/Inter typography, Dual Open Access Web Reader & Print Proof PDF).
   - Apply secondary publisher presets (UI Publishing, Deepublish, Springer, Elsevier) if explicitly requested.
3. Confirm page size; default to `UNESCO` (15.5 x 23 cm) for ID or `Royal/US Trade` for INTL.
4. Design the hierarchy for chapter title, section headings, body text, captions, and notes.
5. Define header/footer patterns, including running title and page number placement.
6. Define chapter opener page style.
7. Provide layout guidance that can be implemented in DOCX, PDF, or desktop publishing tools.

## Rules

- **Default Text Alignment**: ALL body paragraphs in generated layouts, DOCX files, and PDF specs MUST use **Justified (Rata Kanan-Kiri)** alignment by default (`alignment: justify` / `\justifying`).
- **Chapter Opener Layout**: Every new chapter MUST start on a **Recto (Odd)** page with `100-120pt` Space Before (`~4 cm` top offset drop), a 2-tier Chapter Number & Title hierarchy, and different first page header (running title hidden).
- **Paragraph Indentation**: Paragraf pertama tepat di bawah judul bab/subbab **TIDAK memakai indentasi** (*No First-Line Indent*). Paragraf berikutnya memakai *First-Line Indent* sebesar `0.63 cm` (`0.25 in`).
- **Table Formatting**: Use APA 3-Line table formatting by default (horizontal top, header, and bottom borders only; NO vertical borders).
- **Widow & Orphan Control**: Enforce widow and orphan prevention and `keep_with_next` on all headings.
- Prioritize readability over decoration.
- Keep academic pages clean and consistent.
- For buku ajar, include styles for learning objectives, exercises, assignments, and summaries.
- For monographs/reference books, include styles for tables, figures, quotes, and synthesis boxes.
