/* ==========================================================================
   Invite Landing — S7 layout

   Renders inside layouts/auth.html.erb with the auth wordmark suppressed
   (the invite has its own header). Sections, top to bottom:

     1 — Sharer attribution band (compact §5.7) — top of page, most personal
     2 — Header — real Grailsome wordmark + "Sign in" link
     3 — Compressed hero — "FIND YOUR Grail." + tagline
     4 — Sign-up form — email + claim button (the conversion moment)
     5 — Bonus-Moment Card (base §5.8) — visible reinforcement while typing
     6 — Below-fold eyebrow + 3 proof cards
     7 — Footer — wordmark + privacy/terms links
