CAPTCHA showcase

Set a development secret and run:

CAPTCHA_SECRET="replace-with-at-least-32-random-characters" bun run dev

Open the local URL printed by WRNexusJS. The main page exercises number, alphabet, alphanumeric, calculation, image-selection, audio, compact/normal/big sizing, listen visibility, not-robot, invisible timing/honeypot, protected form-submit, and page-gate flows. Open /styles to test all 18 generated text-image renderers, random difficulty modes, allowed pools, and excluded pools.

Run the showcase validation with:

bun run check

The check runs TypeScript validation, the showcase integration tests, and a production build.
