Added a fullscreen mode to the slippery-boxes game page. A toggle button in the header expands the iframe to fill the viewport while maintaining the game’s aspect ratio, hiding the site chrome and dynamically resizing on window changes. The fullscreen state is reflected in the URL via a fullscreen query parameter so it can be linked to directly. Also added a local param for pointing the iframe at a local dev server.

Migrated slippery-boxes to use its new subdomain, cleaned up URL parameter handling, and hid scrollbars in fullscreen mode. Updated the page description and added a screenshot of Ralph.

Backfilled devlog entries for the original slippery-boxes development period covering the initial prototype through gamepad support.
