   SHIVAA v178 — the in-footer app band (PWA install, no store, no APK).
   The old floating install chip is dead (v140, owner-ordered, never
   returns). This band is IN-CONTENT: it lives in the footer flow, never
   floats, never auto-appears as an overlay, and its dismiss sticks.
   Only the iPhone/Android guide SHEET is an overlay — and it opens solely
   on a tap, and closes instantly (button, backdrop or Esc).
