SearchView: Removed the dynamic collection-tile grid (e.g. "پرفروش‌های این هفته") and the "نتایج / N محصول" section header from the UI. Underlying data/filtering logic untouched.

DashboardView ("میز کار"): Rebuilt from scratch with a new structure, distinct from the old card+grid layout but visually aligned with HomeView (same blurred bar, @ink/@wine palette, staged reveal animation on mount):

Single hero card (ink→wine gradient) showing balance, gold/fiat debt, and identity — no quick-action icons inside it anymore.

Live gold rate folded into a slim inline row at the bottom instead of a titled section.
Iterated shadow/spacing on the hero card per feedback (softer, less clipped).
DialogVant / DialogVantOneButton (shared modal components, used in 7+ call sites: Dashboard, Cart, SingleProduct, Register, App): Replaced Vant's default dialog chrome with the app's own rounded-card language — circular icon badge for the illustration, pill-shaped primary/secondary buttons. No call-site markup changed.

LoginView: Rebuilt from scratch — full-bleed dark hero (brand + step copy) overlapped by a floating white form sheet, animated crossfade transition between the mobile-number and OTP steps, same staged entrance animation as Home/Dashboard. All auth logic (API check, OTP stub, session login) unchanged.
