slugify

Converts an input string into a clean, URL-safe slug.

Steps

1. Lowercase the entire input string.
2. Replace whitespace with hyphens.
3. Remove any character that isn't a lowercase letter, digit, hyphen, or apostrophe.
4. Collapse multiple consecutive hyphens into a single hyphen.
5. Trim any leading or trailing hyphens.
6. Return the resulting slug.

Gotchas

• Numbers are kept as-is (e.g. "Top 10 Tips" → "top-10-tips").
• Punctuation like colons, commas, and question marks is simply dropped, not replaced with a hyphen.
