/* ═══════════════════════════════════════════════════════════════════════
   sg.css — StockGenie Pro design system
   ═══════════════════════════════════════════════════════════════════════

   Sep 2026. Every page previously carried its own <style> block, so the
   product drifted: eighteen login screens, each styled separately, no two
   quite alike. This is the single source. A brand change is one edit here
   rather than a search across eighteen files.

   Pages import it BEFORE their own <style>, so anything page-specific can
   still override. Nothing here depends on JS.

   Deliberate constraints:
     · --tap (48px) is a floor for anything touched. Warehouse staff wear
       gloves; a 36px button is a support call.
     · Light tokens exist but dark is the default — that is what the app has
       always been, and warehouses are dim. Set data-theme="light" to switch.
     · Class names match what the existing markup and the JS emit. This file
       restyles; it does not ask anyone to rewrite their HTML.
