/* ============================================================
   AlternateIncomeSource.com — Speed Test CSS
   File: tools/speed-test/speed-test.css

   WHAT THIS FILE DOES:
   → Controls ALL visual design for the speed test page
   → Colors, sizes, layouts, animations — all here
   → Does NOT affect any other page on your site

   HOW TO EDIT IN FUTURE:
   → Change gauge color     → find "--st-accent" and edit
   → Change card look       → find ".st-card" section
   → Change layout/spacing  → find the section you want
   → Change animations      → find "@keyframes" sections

   NOTE: Colors use var(--accent) and other CSS variables
   from your main style.css — so palette switching (cyan,
   purple, gold etc) automatically works on this page too.
