   A reusable full-screen intro: a minimalist SVG character
   walks in from the left, then the headline fades in.

   QUICK EDIT MAP (variables below):
     --landing-walk-duration : how long the walk takes
     --landing-step-duration : length of one arm/leg swing
     --landing-step-count    : number of swings (walk/step)
     --landing-char-size     : character width
     --landing-char-color    : silhouette color
     --landing-bg-1 / --bg-2 : gradient background colors

   Matches walk/step math: walk = step × count.
   Default: 3s = 0.6s × 5  (character ends in neutral pose)
