Why only one
- Mode is orientation, not permission. It tells Home what to prioritize, not what the user is allowed to do.
- Student and Seeker at the same time would pull Home in opposite directions, so Dilly picks one active mode.
- Profile, projects, saved jobs, tracker, Truth Ledger, and Craft artifacts are mode-agnostic. They work in every mode.
- A student who is also actively job-hunting should pick the mode that matches what Home should prioritize this week. Switch later as needed.
Mode is separate from plan tier. Starter vs Dilly is independent of Student vs Seeker vs Holder.
