/* "What does yours sound like?" sound board in the What is tinnitus section (TEST build, v3). Built by tinnitus-what.js.
   Each card carries its own colours as --c (main), --s (soft tint), --d (deep, for text) and --v (wave scroll time).
   The top strip keeps one fixed colour. Look: soft 3D (neumorphism), chosen by Paul over frosted glass on 2 Nov 2026. */
