The Chair Sets the Sightline: Walk the Path From Her Seat to the Door Before Dusk
The route that matters at dusk starts where she usually sits, so check what she can see and what she must pass before the light changes.
Most families think about the front door when they think about leaving. At dusk, though, the walk that matters starts wherever Mom usually sits. If the chair by the window faces the hall, or the sofa sits in the short route to the kitchen, the house can point her toward an outside door before anyone has asked her to go anywhere.

Sit where she sits
Spend one evening watching from her seat, the chair she takes after lunch or the spot she moves to when the light starts to change. Note what she can see from there. A clear line to an exit, including a glass door or a window onto the porch, is worth noticing. You are not trying to rearrange the whole room. You are checking what she would see first when she looks up.
Walk the route at her pace
Take the walk from that chair to each outside door, slowly, the way she would move in the late afternoon. Count what you pass: rugs, cords, a footstool, a cabinet door left open, a basket on the floor. Ask whether she has to turn, reach, or step around anything. Each of those is a place where a short walk becomes a stop, a stumble, or a second try at the handle.
Decide what to move and what to leave
Move the things that sit in the direct line and the things that make the path longer than it needs to be. Leave what she uses every day unless it is blocking the way. A chair she considers hers can stay where it is if you move the table in front of it. Make one change at a time, then walk the route again so you can see what the change did.
Check the route in both lights
Do the walk twice, once in daylight and once at dusk with the lamps on the way you would actually have them. Shadows across the floor can look like a step, and a dark hallway can look like the way out. Put light on the path itself, not on the door alone, and make sure the switch can be reached from her chair without crossing the room.
Name who keeps it that way
Name the person who checks the route on a regular schedule, because furniture moves when visitors come, when a cleaner rearranges things, and when a new piece arrives. A route that worked in one season can be blocked by a delivery in the next. Write the check on the same calendar as the other household jobs, and put the person's name beside it.
