/* AccessibleAudioStudio styles
   Principle: nothing important is ever conveyed by color, icon, or layout
   alone. Styling here is purely cosmetic polish on top of a page that is
   already fully understandable with CSS turned off entirely.

   --color-accent below is GREEN, matching Open Door Design's blue-and-green
   color-pairing guardrail (blue is not a primary interface color). #1B5E20
   was chosen for a verified ~7.9:1 contrast ratio against white text/panels
   — well past AA — but it is a placeholder, not a value pulled from the
   actual DesignPhilosophyAndStandards repository (this environment has no
   access to fetch it). Replace with the exact approved green token when
   available and re-verify the contrast numbers in the comments below still
   hold. */
