"""Canonical CAML (Corpus Article Markup Language) authoring guidance.

Single source of truth for the system-prompt knowledge an LLM needs to write a
valid, well-structured ``Readme.CAML`` article. Reused by every agent that
authors one:

  * the seeded "CAML Article Writer" corpus action
    (``opencontractserver/corpuses/template_seeds.py``), and
  * the corpus auto-branding agent
    (``opencontractserver/corpuses/services/branding.py``).

Two maintained building blocks, composed (never sliced):

  * ``CAML_AUTHORING_GUIDE`` — the tool-agnostic reference (CAML syntax,
    editorial principles, structure template, output rules) that any caller
    layers onto its own task-specific framing.
  * ``_CAML_WRITER_MISSION`` — the framing for the seeded "CAML Article Writer"
    action (research-a-collection mission).

``CAML_ARTICLE_SYSTEM_INSTRUCTIONS = mission + guide`` is the full writer prompt
for that action. Editing either block updates both consumers with no string-
index coupling, so they can never drift.

CAML SYNTAX REFERENCE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

CAML is a markdown superset with YAML frontmatter and colon-fenced \
directive blocks. A document has two parts:

  ---
  (frontmatter - YAML)
  ---
  (body - chapters and blocks)

FRONTMATTER
-----------
```yaml
---
version: "1.0"

hero:
  kicker: "Small text above title"
  title:
    - "First Title Line"
    - "{Accent-Styled Line}"
  subtitle: >
    Multi-line subtitle folded
    into a single string.
  stats:
    - "500 documents"
    - "12 jurisdictions"

footer:
  nav:
    - label: Documentation
      href: https://docs.example.com
  notice: "Copyright 2024 Example Corp."
---
```

Key rules:
- Title lines in {curly braces} render with accent styling.
- Use `>` for multi-line subtitle (YAML folded scalar).
- Stats render as badge-like items below the subtitle.

CHAPTERS
--------
Chapters are depth-3 fences (:::) with type `chapter`:

```
::: chapter {#findings, theme: dark, gradient: true, centered: true}
>! Section 01
## Key Findings

Prose content here using standard markdown.

:::: cards {columns: 2}
(nested block content)
::::

:::
```

Attributes: #id, theme (light|dark), gradient (true), centered (true).
- `>! text` sets the chapter kicker (small text above title). Last one wins.
- `## text` sets the chapter title. Only the first ## is consumed.
- Content inside a chapter that is not in a block fence is prose.

BLOCKS (inside chapters, use :::: depth-4 fences)
------

CRITICAL: every :::: block below MUST live inside a `::: chapter ... :::`. The
per-block examples that follow show only the block fence for brevity — they are
NOT standalone documents. A :::: block placed at the top level (outside any
chapter) will NOT render: the parser cannot close a depth-4 fence outside a
chapter and leaks the block's body to the page as raw text. Always nest, e.g.:

  ::: chapter {#overview}
  ## Overview

EDITORIAL PRINCIPLES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

1. NARRATIVE ARC: Every article should tell a story. Open with a hook, \
build through supporting evidence, and close with insight or a call to action.

2. EVIDENCE-BASED: Every claim must be grounded in the actual documents. \
Use ask_document and load_document_text to verify facts. Never fabricate \
statistics, dates, or quotes.

3. READABILITY: Write for an intelligent non-specialist. Avoid jargon \
without explanation. Use short paragraphs. Vary sentence length. Lead \
with the most interesting finding.

4. VISUAL RHYTHM: Alternate between prose, data blocks, and visual \
elements. Never stack more than 2-3 paragraphs of prose without a visual \
break (pills, cards, timeline, pullquote, etc.).

5. PULLQUOTES: Extract the single most striking sentence or statistic \
from each major section and present it as a pullquote (>>> prefix). These \
serve as visual anchors and scannable highlights.

6. COLOR CONSISTENCY: Choose a cohesive color palette (2-4 accent colors) \
and use them consistently across all blocks. Good palettes:
   - Professional: #0f766e (teal), #2563eb (blue), #7c3aed (purple)
   - Warm: #059669 (emerald), #d97706 (amber), #dc2626 (red)
   - Cool: #0284c7 (sky), #4f46e5 (indigo), #0f766e (teal)

7. CHAPTER THEMING: Use theme: dark for emphasis chapters (key findings, \
conclusions). Use gradient: true + centered: true for CTA chapters. \
Keep most chapters in the default light theme.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
ARTICLE STRUCTURE TEMPLATE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

A well-structured CAML article typically follows this pattern:

1. HERO (frontmatter): Compelling title, informative subtitle, key stats.
2. OVERVIEW CHAPTER: Executive summary with pills showing key metrics.
3. ANALYSIS CHAPTERS (1-3): Deep dives using cards, tabs, or timelines.
4. DATA CHAPTER: Map, timeline, or detailed metrics.
5. CONCLUSION CHAPTER: Key takeaways, often with theme: dark.
6. CTA CHAPTER: Call to action with gradient: true, centered: true.
7. FOOTER (frontmatter): Navigation links and notice.

Adapt this structure to fit the corpus content. Not every article \
needs every element. A 3-document corpus needs a simpler article than a \
50-document collection.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
OUTPUT RULES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

- Output ONLY the raw CAML source. No markdown code fences wrapping the \
output, no preamble, no commentary.
- The article MUST begin with `---` (frontmatter opening).
- Every opened fence (:::, ::::, :::::) MUST be closed.
- Every :::: block MUST be nested inside a ::: chapter. A block at the top \
level (outside a chapter) will not render — its content leaks as raw text.
- Use only safe href values: https://, http://, #, or / relative paths.
- Keep the total article concise but substantive. Aim for 3-7 chapters.
- Include a corpus-stats block when the collection has meaningful metrics.
