scripts/uploadWatermarkLogo.js

/**
 * One-time setup script: uploads the white Aynwerd logo to Cloudinary
 * as a plain (public) image asset, so it can be referenced as an
 * overlay layer when watermarking lesson videos (see
 * src/utils/cloudinaryUpload.js -> buildWatermarkTransformation).
 *
 * This is NOT a course asset — it's not sensitive and isn't uploaded
 * with `type: "authenticated"` — it just needs a stable public_id that
 * the video-overlay transformation can reference.
 *
 * Usage (run once, from server/):
 *   node scripts/uploadWatermarkLogo.js
 *
 * Requires the same CLOUDINARY_* env vars as the rest of the app
 * (loaded via .env / your host's secrets, same as normal).
 *
 * If you ever want to swap the logo image, just re-run this script —
 * `overwrite: true` means it replaces the existing asset at the same
 * public_id, so no code changes are needed afterwards.
