🔤 Regex Tester → +Cheatsheet

A collapsible regex cheatsheet now lives alongside the tester. Anchors, character classes, quantifiers, groups, alternation, escapes, and flags — all with examples. Toggle it when you need a refresh.

🔐 Password Generator → +Passphrase Mode

Generate memorable passphrases — random word sequences that are easier to remember and more secure than complex symbol passwords. Choose 3-10 words with your preferred separator. Entropy is calculated for both modes.
