The seam at the gates

Five things flip at once when she walks through a gate arch, and what stands in the first 40 m.

From inside, the arch is a picture frame and the land outside is a painting hung in it. A player feels the change because five things flip at once.

Through a honey stone arch: butter lanterns, a sleeping guard bear with a mug, flower tubs; beyond, a tall cool land with a leaning pine, a ruin, and a path to a distant range. — Lead image of the seam. Faults: the guard's spear is sharp (nothing sharp is in reach), and the ruin outside is gloomier than 'friendly'.

	Inside the arch	Through the arch
Temperature	honey, cream, butter light	olive, slate teal, pale straw light
Shape	round, chunky, upright	tall, tapered, leaning
Paint	blended, no line	strokes, three hard tones, thin coloured line
Distance	everything within 30 m	the first thing 30 m off, the last 2 km off
Enclosure	framed on both sides	a horizon

The folk do not flip. Human figures have one design on both sides of the wall; what changes on a person is the zone's clothing colours and the ornament (painted rosemaling inside, a woven or carved band outside).

Seven rules, measured from the wall's outside face

They sit inside the engine's blend of 4 m inside to 36 m outside.

Each gate frames one landmark of its zone, at least ten times her height, visible from 20 m inside the gate through the arch (at Nordporten: the old pine and the watchtower).
0 to 10 m out: the cobbles stop at the arch's outer edge; the road turns umber; the last cute thing stands here.
10 to 25 m: the flowers of the gate's two tubs come back as wild drifts of the same colours, in the outside brush. This is the one thread she can follow across.
15 to 30 m: the first leaning or tapered silhouette (a wind-bent tree, a tilted way-marker).
Within 40 m: the first painterly story (a tipped cart at Nordporten, a cold camp at Vestporten, a spilt churn at Sørporten).
Coming home: from 60 m out, the arch shows a warm, round, lit picture in a cold grey-green wall. Both gate lanterns are butter-yellow, the only butter light outside.
Nothing is half and half. No prop mixes the two looks except the gate itself.

Do

Hand the flowers over across the gate: the same colours, inside tubs to outside drifts.
Put exactly one landmark in each arch.
Keep the gate lanterns butter-yellow, seen from outside.

Never

A prop with painted rosemaling and carved wheels together.
A blended zone: half cute, half painted.
A sharp spear or a ruin that is gloomy in the first 40 m.

Seen from the other side

The Eventyrland game has a gate for each road: Nordporten to Nordalen, Vestporten to Fjellfoten, Sørporten to Sørmarka, Sørvestporten to Sørvika. Each has its own colour and emblem on the inside face. The game's docs/wall.md lists them with what stands outside.
