Random Color Generator
Generate random colors using `crypto.getRandomValues` — high-quality randomness, never pseudo-random `Math.random()`. Pick the output format (Hex, RGB, or HSL) and choose a palette constraint to keep results visually coherent: Pastel clamps saturation to a soft range and lightness high; Vibrant maximises saturation around mid-lightness; Dark and Light push lightness to the ends. Useful for placeholder UI, design exploration, identicon-style coloring, or seeding test data. All generation runs in your browser — no API, no upload, no rate limit.
