Add founder story, tighten homepage flow

- A brief, grounded note under "The story scatters" about why Medscribe
  exists — the first real, personal detail on the public site rather than
  only the composite family narrative.
- Drop the "What travels with them" screenshot strip: it re-showed screens
  already covered by the interactive feature tour just above it, adding
  scroll length without new information.
