  Form 15G/H (auto age-based), Hypothecation, NOC - each with shared
  preview dialog (six tone variants) and jsPDF generator using a
  common letterhead / summary-grid / signature-seal helper.

  MMID/mobile lookup, NPCI switch resolve-to-A/C+IFSC BANL flow,

  field reorder (sender before amount), NEFT cap / RTGS floor
  validation, History button opening per-sender today's transactions.
- NEFT/RTGS report: horizontal-bar trend leaderboard replacing tall bars.

shell + theme:
- Header redesigned with IBM Plex Sans 12/500 typography, 11-column grid
  per row, top-accent hover indicator, bordered cells via grid-gap.
- Live KPI ticker below menu (CASH, TXN TODAY, CLEARING IN/OUT, NPA,
  CASA, CD RATIO, RBI CIRC, REPO) with marquee scroll, pause-on-hover,
  brand-blue gradient, amber bottom strip, pulsing red LIVE chip.
- Sidebar 'KYC Management' -> 'KYC & ReKYC Management'.
