What changed in v5.2.5

The game has a home — a retro arcade landing site is now live at superdungeonracer.com:

• Landing site — a retro-styled landing page at the root (/) with the manual, release notes, and live test results; PLAY links to the game at /play. A newsletter signup is wired (signups are logged as a fallback until a datastore is added).
• Custom domain — the site is served at superdungeonracer.com (apex + www) with auto HTTPS. The favicon is now the game's own icon.
• Smaller web download — test/dev directories were excluded from the exported .pck, so the player download dropped from ~303 MB to ~220 MB with no game assets touched.
• Security hardening — strict CSP on the first-party pages, security headers site-wide, rate-limited newsletter endpoint, and a canonical-host + HTTPS redirect so root-relative links always land on the working host.

No in-game changes since v5.2.4 — this release is the web home.
