To use your own background photo and EP logo, upload two image files alongside your HTML files on Netlify, then update platform.css:
Background photo — change --bg-photo: url("library-bg.jpg") to your filename. Recommended: 1920×1080 px, warm library/bookshelf scene.
EP logo — change --logo-photo: url("ep-logo.png") to your filename. Recommended: transparent PNG, min 200×200 px. If missing, "EP" text shows instead.
Adjust darkness — change --bg-overlay: rgba(8, 4, 1, 0.70). Raise the last number (0–1) to darken, lower it to show more photo.
Fill in fields and click Generate. Copy the output into the AUTHORS array in authors.js — no other files change.
