Reading the map
Window band: note where outdoor LEDs or street reflections enter; layered curtains often spread contrast more evenly than a single sheer panel alone.
Rest surface: keep chargers and bright screens away from pillows if you prefer a darker visual field.
Lamp stack: combine overhead dimmers with a low table lamp so tasks near the floor remain visible without lifting the whole room to daylight levels.
Textile buffer: rugs and drapes tame echo; the change is subtle yet noticeable when audio sources sit close to hard walls.
