/* ==========================================================================
   AppsS Technologies — "Clean Fintech" theme (dark + light)
   Loaded after style.css on pages that opt in. Pages that don't load this file
   keep the original neon look untouched.

   How it works: style.css draws every translucent colour from rgb "channel"
   tokens (--ink-rgb, --accent-rgb, ...). This file redefines those tokens per
   theme and refines shapes, spacing, type and glow.
