Subject: [PATCH] Fix: pages/CSS 404 on URL-encoded links (double-decode broke
 UTF-8 filenames)

Express already decodes req.path; the extra decodeURIComponent re-decoded
UTF-8 filenames and returned 404 for URL-encoded links (as used by the
original site), so page CSS didn't load and buttons looked unstyled.

Now all 41 pages + all CSS/assets serve 200 via encoded URLs; 0 404.
