Password Strength Meter with Live Rule Checklist (Vanilla JavaScript)

A password strength meter that scores input live against five common rules - length, lowercase, uppercase, number and special character - lighting up a color-coded bar and checklist as you type. Includes a show/hide toggle and clear Weak/Fair/Good/Strong feedback. Pure vanilla JavaScript and CSS, no dependencies, ready to drop into any signup or account-settings form.
