   Codemola Retail — app.css

   Aesthetic direction: refined utility. Used by cashiers ringing 8-hour
   shifts and shop owners reviewing books at 11pm. Cannot be flashy.
   Must be calm, dense, fast, scannable.

   Choices:
     - Warm off-white (#faf8f3) instead of stark white. Easier on tired
       eyes than #fff. Inspired by paper, not screens.
     - One confident accent: a deep teal (#0e7c7b). NOT purple, NOT
       indigo. Reads as professional without being banking-app generic.
     - Typography: ui-serif for headings (gives just enough personality
       without web-font cost on shared hosting), system-ui for body.
       No web fonts loaded — every request matters on cPanel.
     - Borders, not shadows. Sharp 1px lines feel honest; soft shadows
       fight the calm aesthetic.
     - Generous line-height (1.55) for body, tight (1.2) for headings.
       Numbers tabular for money columns.

   Not a CSS framework. Not Tailwind. Hand-written so we control every
   selector. ~12KB uncompressed.
