 **Formatting rules:**
+- **Do not hard-wrap text like a commit message.** A PR description is not a commit message: never break paragraphs or bullet points at a fixed column width (e.g. 72 characters). Write each paragraph and each bullet point as a single continuous line and let it soft-wrap. GitHub-Flavored Markdown renders a single newline inside a paragraph as a hard `<br>` line break, so commit-style wrapping makes the description render with line breaks mid-sentence. Only use blank lines to separate paragraphs, list items, and sections.
 - Use clean, standard markdown (no HTML entities, no non-printable characters)
 - Use backticks for file paths, type names, and code references
 - Keep bullet points concise

+Add comprehensive Copilot instructions documenting the CsWinRT 3.0 architecture, build pipeline, and coding conventions.
 
 ## Motivation
 
-The CsWinRT 3.0 codebase is complex, with multiple interrelated build
-tools and a multi-phase build pipeline. Having detailed Copilot
-instructions helps contributors and AI assistants understand the
