- 저장 (Ctrl+S) downloads <교량명>_교각설계.pzr.json; 프로젝트 열기 reads it
back and regenerates every pier without the source workbook.
- Save status in the header: 저장 전 / 변경 있음 · 미저장 / 저장됨. The
snapshot excludes the history so a save is not counted as a change.
- Auto-backup to IndexedDB 0.8 s after changes while unsaved; on start a banner
offers recovery or discard. Storage failures are reported, not fatal.
- beforeunload warns while there are unsaved changes.
- B1 (default-vs-changed tracking) is not added yet: inputs are not editable
until the 2단계 input cards exist.
- Not verified in a browser (no debuggable Chrome in this session).

- Footings, blindings and piles on a bent axis are placed in their stretch's
frame; 일체기초 is grouped per stretch, so a combined footing never crosses
the kink (separate footings, each aligned with its stretch).
- Footings, blindings and piles are trimmed at the mitre plane like the coping.
- The stage-2 refusal for bent foundations is removed; the Level-half-width
refusal for columns at the kink remains.
- Tests: T형 footing crossing the kink stays in stretch 0; 2주형 with columns
on both sides gives one footing per stretch, with mitre clipping in the scene.

- buildPier builds on buildAxis: each object carries its stretch k and a local
s from that stretch's base; coping parts are per stretch with the mitre plane
trimming the overlap in the scene (renderer.localClippingEnabled).
- Straight P1 output is unchanged (regression tests pass).
- Bent coping is supported for 현장타설말뚝 only; footings and piles on a bent
axis remain 미실시 until stage 3. Kink outside the coping and columns within
the Level half-width of the kink are refused.
- W03/W04 use coping coordinates (g).
- Tests: constructed 60° bend — world coordinates of bearings, blocks and the
column survive the stretch frames; mitre sides; scene mesh count; refusals.

- Front and back coping tops that differ by 5 mm or more in any segment are
drawn as two coping parts split at the midline between the bearing rows.
Tolerance 5 mm and midline position are the draft assumptions (Q1·Q2).
- Scene extrudes each coping part across its own width.
- solveIp4 computes IP4 as the intersection of the IP1→IP2 line with the
line through IP3 turned by the bend angle (positive = counter-clockwise,
sign convention to be confirmed). Bent coping geometry remains 미실시.

- three.js scene in the pier frame (pivot at first column centre)
- coping as extruded elevation outline; columns, footings, piles, blinding, bearing blocks and pads
- four view presets, per-part visibility toggles
- workbook load (sample or file), result table, issue list and undetermined defaults
- frame orientation test and bounding-box test
