/* ===========================================================================
   Sevgi Pınarı ERP — the one style sheet of the application.

   HOW IT IS ORGANISED
     1. Design tokens   colours, sizes: change the look of everything from here
     2. Base            page, text, links
     3. Layout          menu (sidebar), top bar, content area
     4. Components      buttons, cards, tables, forms, badges, dialogs ...
     5. Screens         the few rules that belong to one screen only
     6. Helpers         small utility classes (.muted, .row, .stack ...)
     7. Print

   RULES
     - Phones first: every rule is written for a narrow screen, then widened
       with "@media (min-width: …)".
     - No style is written inside the HTML (the browser is told to refuse it,
       for security). Everything visual lives in this file.
     - A catalogue of all components, with the HTML to copy, is in
       docs/07-erp-design-guide.md.
