/* ==========================================================================
   smartdomprof.pl — global stylesheet  v3
   DARK-ONLY, MOBILE-FIRST, FULLY FLUID.

   Design contract:
     - Dark is the ONLY theme. There is no light variant (print excepted).
       color-scheme: dark tells the browser to render scrollbars, form
       controls, autofill and the address bar chrome dark too.
     - Base styles target a 320px phone. Every @media rule scales UP.
     - Typography is fluid via clamp(): no jumpy font sizes between
       breakpoints, no horizontal overflow at any width.
   Breakpoints: 360 / 480 / 600 / 900 / 1200 / 1600
