   Become an Instructor — "Why iGurus" section
   External stylesheet (per request: new component CSS lives here,
   not inline/internal <style> blocks in the blade file).
   Reads the page's own --bi-* tokens defined in become-instructor.blade.php.

   Colored top-bar cards — same red/amber/green rotation as the
   Affiliate page's .igaf-step / .igaf-metric cards, kept to a flat
   white card + thin top bar (no icon-square color, no gradients).
