New shop-packet output: a printable cost estimate driven by the active
CutPlan's buy-counts × a curated, editable price book (HST 15%).
- prices.py: DEFAULT_PRICES seeded with real Kent (New Brunswick) shelf
prices per buy-unit (lumber = 8' stick, plywood = 4x8 sheet); persisted to
$XDG_CONFIG_HOME/woodshop/prices.json (defaults + saved overrides).
estimate() -> CostEstimate (lines/subtotal/tax/total/missing); lumber price
scales with stick length; unknown stock is flagged, never invented.
- BOM window: Cost tab with "Edit prices…" (PriceEditDialog), "Refresh from
Kent…", and Print.
- fetch_kent_prices() + scripts/fetch_kent_prices.py: best-effort refresh.
Kent renders prices client-side (not in HTML), so it tries a static parse
then Playwright if installed — honest that it may need updating.
- tests: estimate math, per-sheet plywood, stick-length scaling, missing-price
flagging, save/load roundtrip, corrupt-file fallback, JSON-LD parse, cost
tab render + price edit persistence. 153 passing.
