Cookiemonsters

Imported from the pre-Redmine CookieMonsters TODO during the 2026-08-29 migration.

Original priority: P1 — Community experience and polish

• Add optional watermarking for member images later:
  • watermarking is an optional deterrent/ownership aid, not a substitute for the permission system above;
  • let each member choose whether images should receive a watermark;
  • support a member-selectable watermark style/content later, e.g. CookieMonsters username/display name and/or a custom watermark label;
  • consider position, opacity and size controls without making the upload flow complicated;
  • preserve the protected original separately so watermark rendering can be changed later without permanently altering the source image;
  • decide later whether watermarking applies globally per member, per folder, per image, or a combination with sensible inheritance/defaults.
