 * AIS-TIP V5.6.7 / Final Comprehensive Lock
 * Final production-oriented polish on top of V5.6.6:
 * - slightly lighter shell tonality
 * - clearer foreground / background depth rhythm
 * - more balanced label distribution left/right/up/down
 * - refined label typography and calmer point presence

   * Keep the lower shell fully readable until 24px before that occlusion edge,
   * then fade only in the short approach to the card. This replaces the old
   * 78%→100% long fade that weakened ~43px of still-visible shell too early.
