Edit the attached TOP-DOWN SITE PLAN image: draw STAGING MARKERS on it
at the positions described below. This is a planning aid for a film
crew, drawn over the plan.

PLACEMENT AUTHORITY: each marker line below gives its position as
normalized fractions of this canvas — x runs left→right 0..1, y runs
top→bottom 0..1 — and THOSE FRACTIONS ARE THE AUTHORITY. Measure them
on the attached image and put the marker there. Each line also names a
nearby landmark; use it to check you landed on the right feature, and
when a landmark phrase and the fractions disagree, follow the
fractions. This applies to compass words (north, south, east, west)
too: read them only if this plan actually shows a compass or labels
its own approaches, and even then they never move a marker away from
its fractions. Do NOT relocate a marker onto a different salient line
or feature than the one its fractions land on.

NEVER move a marker to make the drawing fit. The camera circle and
every subject circle go exactly where their descriptions place them,
even when that leaves the view wedge or an arrow running off the edge
of the image — in that case just let the wedge or arrow continue to
the image border and stop there. Shifting the camera outward, pulling
a subject aside, or shrinking the wedge to keep it inside the canvas
all break the plan this map exists to record.

Draw EXACTLY these markers, flat and high-contrast, small enough not
to hide the plan under them:
- CAMERA: one filled circle at the camera position, labelled CAM, and
  out of that circle a FIELD-OF-VIEW WEDGE showing what this shot
  sees — two straight thin lines, one running toward each of the two
  frame-edge positions given below, and a third thinner line to the
  look-target position between them. Fill the area between the two
  edge lines with a light translucent tint so the wedge reads as the
  camera's view; the plan underneath must stay fully readable through
  the tint. Every subject listed below stands inside this wedge —
  if your drawing leaves one outside it, the wedge is drawn wrong,
  not the subject.
- SUBJECTS: one filled circle per subject at its position, labelled
  with its slot code (E1, E2, ...) followed by its short description
  in parentheses, and one short ARROW leaving that circle toward the
  spot the subject faces, so the direction each subject is turned is
  readable at a glance.

Change NOTHING else: keep every zone, landmark, line, label and color
of the plan exactly as attached — do not redraw, recolor, move or
remove anything, do not add scenery, shadows or any other symbols or
text beyond the markers, wedge, arrows and labels specified above. The
output is the SAME plan image with only these staging markers added.
