+## Tone
+
+- Conversational - like talking to a colleague, not writing a textbook
+- Direct - get to the point, no throat-clearing
+- Honest - don't oversell, say what it does
+- No emdashes (use normal -), no marketing buzzwords, no "revolutionary"
+- Never use "load-bearing" or "load bearing"

+- **Bold**: sparingly, for genuine emphasis only. Never bold every other word.
+- **Italics**: avoid entirely - hard to read, rarely adds value. Use `code` for
+  technical terms and bold for emphasis instead.
+- **Emojis**: fine in moderation (section headings). Never in code examples or
+  as bullet substitutes.
+- **Code blocks**: always specify the language.
