Repetitive emoji on every header

Applying 🦔 to all 10 headers adds the same decoration at every level (including subsections like ### Prerequisites) without conveying any additional information. When every heading carries the same symbol, it becomes visual noise rather than a meaningful brand signal. Per the simplicity rule "has no superfluous parts," a single emoji on the top-level title (or at most the top-level ## sections) would brand the file without repeating the same glyph throughout.

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!
