Instructions
1. Drag the "Text Selection Disabler" element onto any page where you want to disable selection.
2. Configure options: Apply to page (yes/no), Target selector (CSS), Allow selectors (comma-separated to allow selection).
3. To disable the iOS dictionary/lookup on long-press, ensure "Disable touch callout" is ON.
4. To exclude inputs (so users can still copy/type), add `input, textarea, [contenteditable="true"]` to "Allow selectors".
