CONFIRMED FACTS (override any résumé guess):
- Preferred contact email: {f["preferred_email"]}
- {f["citizenship"]}. {f["work_auth"]}
    * "authorized to work where the job is located?" -> YES if the role is in India, NO if US.
    * "require visa sponsorship?"                     -> NO if India role, YES if US role.
  Honesty over optimism — never overstate authorization.
- {f["availability"]} Today is {today:%Y-%m-%d}; for a start-date picker choose a FUTURE date near
  {soon:%Y-%m-%d}, never a past date.
- MOTIVATION: for any "why this role" / "about you" / "additional information" free-text field,
  write a genuine 2-4 sentence answer TAILORED to THIS specific job (use its title / company /
  description visible on screen) grounded in the candidate's real background above. NEVER leave it
  blank — a blank motivation makes a weak application.
