Password strength checker

Most strength meters score whether you used a capital letter, and rate "Manchester2024!" as unbreakable. This one decomposes what you type the way a cracker does — un-doing letter-for-symbol swaps, matching the core against a dictionary of common words and names, and treating an appended year or trailing symbol as the cheap mangling rule it is — then converts the guess count into time-to-crack at modern offline hash rates. Nothing you type leaves your browser.
