YAML Backtick Bug Fix | Generated by AI
All tests pass. Here’s what was wrong and what I fixed:
Root cause — Two post files had backticks `ll uno` in their YAML front matter title field. Unquoted backticks are invalid YAML tokens (YAML parser sees the ` as a character that can’t start any token), which caused the front matter parsing to fail silently and the test to catch it.
Files fixed:
_posts/en/2026-07-13-ll-uno-arduino-serial-monitor-en.md_posts/zh/2026-07-13-ll-uno-arduino-serial-monitor-zh.md
Fix: Wrapped the title values in double quotes with single quotes inside: title: "'ll uno' Arduino Serial Monitor" — this is valid YAML and preserves the intent of code-formatting around ll uno.
