   16) Quick tuning knobs
   ========================= */
/*
If the logo still looks too small because your PNG has whitespace:
  Increase: --logo-scale: 1.30;
If it looks too big:
  Decrease: --logo-scale: 1.12;

Button color tuning:
  --btn-solid: #2f7d1e;
  --btn-solid-hover: #256618;
  --btn-solid-active: #1f5714;

Pulse tuning:
  In .preview animation:
    2.4s -> faster (more noticeable)
    3.0s -> slower (more premium)
