/* MediSense — medisense.in
 *
 * ADMIN 2026-09-26: "it must reflect our app's UI exactly, proper logo and
 * proper functionality, so a user is never confused with other sites —
 * it's MediSense, it's a brand."
 *
 * So nothing here is a designer's interpretation. Every value below is read
 * from the app's own locked tokens:
 *
 *   lib/core/design_tokens/medisense_physical.dart   surfaces + shadows
 *   lib/core/design_tokens/medisense_palette.dart    brand colours
 *   lib/main.dart                                    GoogleFonts.lora()
 *   lib/core/design_components/ms_physical.dart      _raisedShadows()
 *
 * Three things were wrong before and are corrected here:
 *
 *   1. TYPEFACE. The app is set in LORA, a serif. The site used Archivo,
 *      a grotesque. That single difference stopped it reading as MediSense.
 *   2. DARK GROUND. The app's dark identity is GREY (#616870 page, #545454
 *      face) — locked after on-device approval. The site used voidNavy
 *      #0E0E22, which is near-black. ADMIN: "without dark mode app looks
 *      totally black in colour."
 *   3. SURFACES. The app is neumorphic: a white highlight offset -6/-6 at
 *      blur 15, and inkNavy at 64% offset +6/+6 at blur 17. The site used an
 *      ordinary drop shadow.
