What changed, and why it matters
This commit is a minor formatting edit to the README.md file. It changes a 'Security Advisory' heading from being displayed as a code block (with diff-style coloring) to a normal Markdown heading, and adds a horizontal rule. There are no code changes, no new security claims beyond what was already present, and no functional impact on the COLDCARD firmware.
No action required. This is a documentation formatting change with no security or operational relevance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff only modifies README.md presentation: it removes the triple-backtick code fence markers around an existing security advisory section, converts the heading to a standard Markdown H1, and inserts a horizontal rule. The underlying security advisory text about a historical entropy bug remains unchanged. No source code, build scripts, or firmware logic were altered.
