### Variables Mismatch
These are the most critical - placeholders must match exactly:
- Check that all \`{placeholder}\` variables from source appear in translation
- Don't translate placeholder names (e.g., \`{days}\` should stay \`{days}\`, not \`{jours}\`)
- Include \`$\` for currency placeholders (e.g., \`\${price}\`)

### Punctuation/Special Characters
- Ensure ending punctuation matches (periods, question marks, etc.)
- Check parentheses and brackets are balanced

### Spellcheck
- Often false positives for technical terms - can usually be ignored
- Review for actual typos
