1) Quote card header: an official/unofficial badge (رسمی / غیررسمی) renders next to the supplier name from quotes.is_official (the «فاکتور رسمی» checkbox) — green for official, muted slate for unofficial.
2) Conversion Factors sidebar: the material group and variant labels no longer truncate with ellipsis — whitespace-normal + break-words so long Persian names wrap cleanly to the next line.
3) Global fixed conversions are now seeded in the unified seeder (app/db/init_db.py — the same file that seeds categories, base units and the superuser path), NOT hardcoded in the frontend: تن→کیلوگرم (1000), کیلوگرم→گرم (1000), هزار عدد→عدد (1000). The supporting units (گرم, هزار عدد) were added to the idempotent BASE_UNITS seed; inserts use ON CONFLICT (from_unit, to_unit) DO NOTHING against the uq_standard_conversion key so every startup is safe. Verified live: 3 rows after first boot AND still 3 rows after an api restart.
4) Universal proforma attachments: the Edit modal now has a پیشفاکتورها section (list/upload/delete via the existing MinIO-backed files API) alongside the invoices section, active at every quote lifecycle stage — including accepted/arrived and receipts-locked quotes (the section is deliberately not gated by hasReceipts; the backend already permits uploads in any status). View/delete of existing proformas unchanged elsewhere.
5) EditModal fixes: (a) the supplier Combobox no longer opens on mount — Radix Dialog autofocus was triggering its onFocus; Combobox gains an openOnFocus prop (default true) and the modal passes false, so the dropdown now opens only on explicit click or typing; (b) the line-item material field binds to the material's own name (m.name) instead of its category relation, and the save path matches materials by name+brand+specs accordingly.
Validated: python compile, api + frontend image builds (tsc + vite) clean; seeding verified against the live local DB.
