MARKER STYLE (paste into every prompt; keep it word-for-word identical across the whole set)

Exterior / plan:
Drawn by hand as an architect's alcohol-marker presentation rendering with a black fineliner on white marker paper -
bold, confident marker strokes with visible parallel stroke direction, layered cool-grey and warm-grey marker tones
for shade and cast shadows, selective colour only (warm ochre-brown timber, sage and moss-green foliage built from loose
marker dabs, pale blue-grey glass with diagonal white highlight strokes), crisp ink outlines with slightly overshooting
construction lines, white gel-pen glints. White walls are shaded with light warm-grey marker, never left blank.
No text, no lettering, no signature, no people, no cars.

Interior:
An architect's alcohol-marker interior presentation rendering on white marker paper, eye-level one-point perspective,
bold confident marker strokes with visible parallel stroke direction, layered cool-grey and warm-grey marker tones for
form and shadow, selective colour accents only - warm honey and ochre timber, sage greens of plants, soft fabric
colours - and the lights are ON: a warm amber-yellow marker glow pools around every lamp and on the nearby walls.
Crisp black fineliner outlines with slightly overshooting construction lines, white gel-pen highlights. The drawing
fades out into the white paper at its four edges with loose hatched marker strokes, like a vignette.
No people, no animals, no text, no lettering, no signature.
