# The FURNITURE flagship — a two-bedroom flat, furnished with the whole symbol catalogue.
#
# Every other example draws a fixture or two in passing. This one is here for the drawn
# symbols themselves: thirty-eight of the eighty-three catalogued kinds, across all five
# indoor domains (bath, kitchen/utility, bedroom, living/dining, office/misc). It is a
# two-bedroom flat rather than a showroom, so the ceiling on that number is the FLOOR
# AREA, not the catalogue: every piece here is somewhere a real one would go, and the
# linter is what says so -- no piece floats off its wall, backs onto the room, blocks a
# door, eats a clearance or collides with anything. `arch validate --strict` reports
# exactly ONE warning, named here so it is not mistaken for rot: `W_PATH_TOO_NARROW` on
# the walk into the kitchen, which the nav grid measures at 400 mm through the 1200 mm
# opening. It appeared when that rule started reporting a MEASURED way in instead of a
# fabricated 0 mm, and it is left standing rather than nudged away -- moving a piece to
# silence a measurement is how a plan stops being evidence.
#
# Four things to read off the source rather than the picture:
#
#   1. NO LABELS. A drawn symbol ignores `label` — the word reaches `describe()` and
#      nothing else — so the only text in this drawing comes from the rooms.
#   2. MOST PIECES CARRY NO SIZE. `against wall <id> … in <room>` takes the catalogued
#      footprint (a fridge is 600 along the wall by 650 deep) and derives the rotation
#      from the wall, so a fitted kitchen, a plumbed bathroom and a bed with its
#      headboard on the right wall are written without a single hand-computed number.
#      `offset` is where the piece's CENTRE lands along the wall run, so a kitchen run
#      is written as a sequence of centres, not as corners.
#      Only the free-standing pieces — the L-sofa, armchair, coffee table, dining table,
#      island, desk, office chair, plant, rug, piano and lounger — declare a `size`,
#      because with no wall there is nothing to tell `along` from `depth`.
#   3. THE RUG IS AN UNDERLAY. It is walked on rather than round, so the pieces standing
#      on it raise no overlap warning and the circulation flood-fill crosses it. Rugs,
#      alone among the symbols, are drawn unfilled — nothing they are written after can
#      be hidden by them.
#   4. THREE PIECES ARE OVERHEAD, and the drawing says so with a dashed outline: the
#      range hood sits over the stove at the same offset, the mirror over the basin at
#      the same offset, and the wall cabinet over its length of the east wall. A thing
#      above the cut plane and a thing below it cannot collide, so those pairs raise no
#      overlap warning — but unlike the rug they are still obstacles to a walk, because a
#      body is taller than a wall unit's underside. That is the whole difference between
#      the two flags, and it is why this plan can draw a kitchen that is actually fitted.
