Canonical rules and HTML/CSS contract for inline `[n]` citation references, end-of-document Citations blocks, and optional per-section citation recaps used across Moody's Agentic Solutions HTML report skills (earnings-brief, peer-analysis, issuer-brief, sector-brief, etc.). Parent skills must read BOTH this `SKILL.md` (rules, numbering, hyperlink behavior, source data shape) AND `assets/template.html` (canonical CSS block + literal HTML markup snippets) before emitting citations. The asset file is the single source of truth for the visual/markup implementation; this `SKILL.md` is the single source of truth for the authoring rules. Triggers when the user asks about citations, sources, references, footnotes, hyperlinking [n] markers, or the Sources/Citations block in any HTML report skill.
