Redesign the complete UI/UX of POSLab — an offline-first point-of-sale platform for restaurants and retail

POSLab is a working POS product (India-first, expanding) with two core surfaces: a touch-first POS app used on Windows tills and tablets by waiters and cashiers during rush hours, and a Back Office web console where owners and managers run menus, floors, printers, staff, and reports. We're commissioning a ground-up visual and interaction redesign of both.

What makes this different from a generic POS shot:

- Offline-first is the architecture, not a feature. Every screen renders instantly from local data — the design must never depend on spinners, loading states as primary states, or "waiting for server" moments. Online and offline must feel identical.
- Restaurant flow is the heart: floor/table map → order taking → kitchen tickets (KOT) → running bills → split/settle → thermal receipt. Speed matters: a waiter takes an order in seconds, standing, one-handed, mid-noise. Fat-finger-proof touch targets, minimal taps per action.
- Hardware is visible in the UI: printer status, cash drawers, kitchen displays, USB/LAN/Bluetooth device management — status truthfulness matters to us (a device we haven't checked shows "unknown", never a fake "online").
- India-market specifics: ₹ everywhere, veg/non-veg markers (these are regulatory-fixed marks, not decoration), GST billing, multi-language (English, Hindi, Marathi, Tamil).
- One accent color themes the product (currently emerald); semantic colors (success/danger/warning)ay fixed. We want atoken-based system a dev team can implement — not just beautiful shots.
Deliverables we'd value: a coherent design system (tokens, type scale, components, density rule vs touch-first POS), the key flows above at real resolutions (1280×800 till, tablet, phone for the
manager-on-the-go), lighline states treated asfirst-class.

Style direction: minimalist and professional — calm surfaces, strong hierarchy, generous toucity in Back Office. Think "a tool staff trust at 9pm on a Saturday," not a landing page.
