/*
 * Stylesheet for the BanWaves placeholder dashboard page.
 *
 * Colours and typographic choices are based on the BanWaves website.  
 * BanWaves uses the Inter font family imported via Google Fonts【531428058125217†L0-L8】,
 * a dark slate background (`bg-slate-900` → rgb(15,23,42)【531428058125217†L840-L846】) and
 * bright accent colours like blue (`text-blue-500` → rgb(59,130,246)【531428058125217†L840-L910】) and indigo.
 * We blend those colours with a gradient backdrop inspired by Deblock's aurora effect【480148680030636†L597-L606】.
