4d2282f546 refactor(timetable): extract computeStageRowHeight helper; StageHeaderCell takes :row-height-px prop (B2) 
Pure structural seam — no layout changes yet (B3 wires the page through).

apps/app/src/lib/timetable/row-height.ts (NEW):
  computeStageRowHeight(laneCount, laneHeightPx, lanePadPx) — one-line pure
  function with the existing math: max(1, laneCount) * (laneHeight + lanePad) + lanePad.
  Math.max(1, laneCount) keeps an empty stage row visible at single-lane
  height instead of collapsing.

apps/app/src/components/timetable/StageRow.vue:
  Switches its inline rowHeightPx computation to call the helper. Behavior
  identical (the math was the helper's body).

apps/app/src/components/timetable/StageHeaderCell.vue:
  New optional `rowHeightPx?: number` prop. When provided (B3 will pass it
  from the page via the same helper), the header root applies blockSize
  inline so the sticky-left column aligns pixel-for-pixel with the row.
  When omitted, the legacy `block-size: 100%` CSS still applies — every
  existing call-site keeps working.

apps/app/src/lib/timetable/index.ts: re-export the new helper.

Tests still green (389 across 54 files); typecheck clean.

36525e729a feat(timetable): pure logic ports — snap, lane, conflict, b2b, capacity, time-grid (Session 4 step 2) 
Ports the prototype's helpers.js + cascade-bump algorithm into typed
TypeScript modules in apps/app/src/lib/timetable/:

- snap.ts        — 5-minute snap (RFC D7) + 15-min minimum duration
- time-grid.ts   — pixel ↔ minute ↔ ISO-8601 coordinate conversions
- conflict.ts    — same-stage same-lane overlap detection (RFC D5)
- b2b.ts         — back-to-back marker links, 3-min threshold (RFC D26)
- capacity.ts    — 110% over-capacity warn level (RFC D25)
- lane.ts        — two-pass resolver + drag-preview cascade (D13/D18/D19,
                   client-side preview only; server is authoritative)

All functions are pure (no Vue, no DOM). Tested in Phase C.
