Room marks are generated at build time from this room’s own record: the rungs it is worked at, its floor area and its air class.

Why this carrier here

Nobody chooses a bedroom scent consciously after the first ten minutes. The nose habituates, the room stops registering, and what is left is the accumulated exposure across a whole night. A rung that feels pleasantly faint at 22:00 is usually the right one at 02:00.

The room is closed for most of its occupied hours, so nothing dilutes the output. Two carriers in a 14 m2 closed room do not add up to a nicer smell; they add up to one carrier's worth of scent plus a headache.

Fabric is the dominant surface here — duvet, pillows, curtains, a rug. Scent that settles into textiles stays readable in the morning even after the air has cleared, which is why low-output carriers and textile formats pair unusually well in this room.
