From KC's 2nd review:
- z-order: boundaries, preamble bands and container frames drawn behind; figures,
responses and parts on top (a figure's description tooltip is no longer blocked
by the preamble box). Preamble + containers are pointerEvents:none.
- the 'large box around all content' is gone: a container renders as a small
corner tab (label + total marks), not an enclosing box; intermediate part-groups
keep a faint dashed nesting frame. Main-question extent is shown by its boundaries.
- MC 'tick N' count (select_n) surfaced next to the option boxes.
- fixed the spurious 'overlapping shapes' review flag on containers (they legitimately
enclose their children; only genuine partial overlaps between non-containers flag now).
tsc clean; 7/7 model tests pass.

From KC's review — the canvas now draws the detail the spike detected:
- numbered sub-answer bands ('suggest two' → dashed dividers + 1/2 labels),
- per-option MC selection boxes (drawn from meta.boxes rel coords; filled tint
when detected marked),
- the final-answer line's expected quantity + unit pill.
Region meta (components/boxes/final_answer_line + figure name/desc) is carried
through load→shape props (metaJson)→render, and round-trips on save via
exam_response_areas.meta. tsc clean; 7/7 model tests pass.

Round-trip fix (item 5): serializeCanvasShapes no longer re-derives the question
tree from boundary pairs (which flattened 3-deep → 2-tier). The whole tree is now
carried as 'part' shapes that hold parentId + isContainer + depth; save preserves
the real parent_id chains (persisted parent wins; geometry is only a fallback for
manually-drawn shapes). Boundary-pair synthesis is kept but attaches to a covering
container box when one exists. New test locks a 3-deep Q→part→subpart round-trip.
Draw structure (item 4): shapesFromTemplate now draws containers too (were skipped),
each with nesting depth. examCanvasShapes renders container frames (transparent,
depth-hued border), PRINTS MARKS on part/container boxes (◆N pill; were never
drawn), and NAMES context figures (figure name as label + description tooltip +
'→ Q' tether pill; was an anonymous purple box). Context name/description round-trip
via exam_response_areas.meta.
Threads new shape props through the tldraw util + setup page + types. Adds meta to
ExamResponseArea + replace payload. tsc: no new errors; 7/7 model tests pass.

The extraction service types every answer space (multiple choice, draw-on, table,
ruled lines…), but the canvas rendered them all as a generic blue 'Response' box.
Add a small form badge (bottom-right) so the recognition is legible at a glance;
context regions show their type too. Colour-by-kind is unchanged.

The S5-7 review layer could surface unconfirmed AI shapes but had no way to
resolve them (confirmed was never set true), so the only "dismiss" was deletion
and the unconfirmed count never dropped. Add the resolution loop:
- A floating review-actions panel (shown while unconfirmed > 0): Accept selected,
Reject (delete) selected, and Accept all AI on the page. Accept flips
props.confirmed = true.
- Human edit = implicit confirm: nudging/resizing an AI ghost marks it confirmed
(R3.3 — a teacher who adjusts a suggestion has reviewed it). Geometry-only
trigger, so the confirmed-only update can't recurse.
- Confidence-driven opacity: unconfirmed ghosts fade by confidence instead of a
constant 0.72; confirmed AI renders solid with its kind icon (like manual).
- Live review counts read straight off the canvas so the unconfirmed chip/panel
update immediately on accept/reject (the old count reflected only saved state).
Persists through the existing PUT (confirmed already round-trips). No schema or
API change.
