Rooms
Essay, Research, Product, Notes — four doors, no public corridor.
A room has a door. A mode has a switch. Hikari uses rooms so you notice when the work has changed.
Essay
Dawn. Long work. The lamp traces argument, not ornament. No outline from a blank page.
Research
Afternoon. Sources stay on the table. The lamp may ask what is missing. It may not summarize unread work.
Product
Late day. Interface copy, letters to customers, the sentence on a button. Two alternatives in the margin, then stop.
Notes
Anytime. A pocket for a line you overheard. The studio will not turn it into a thread or a task list.
Changing rooms
You close one door and open another. Paste is allowed. The house will mark that the page has moved. It will not silently apply Product voice to an Essay.
