/*
 * KikundiDesk — the group's desk. One stylesheet for the public door and the app.
 *
 * The design language is the one already used on www.betki.co.tz: Apple's greys, the #0071e3 accent,
 * Inter, a frosted-glass header, pill buttons, 1rem card corners, large-blur low-alpha shadows and the
 * easeOutQuint spring. The TOKENS are ported from that theme's variables.css so the two surfaces cannot
 * drift apart; the COMPONENTS below are written fresh, because a marketing page and a working tool want
 * different things. The 100vh gradient hero belongs on the door, never inside the desk.
 *
 * Inter is SELF-HOSTED (public/fonts/), never a CDN — the same reason lib/report-charts.js draws its own
 * SVG: this runs on a box whose outbound access we do not control, and a katibu on a Dar es Salaam phone
 * should not wait on fonts.googleapis.com to read what their group owes.
 *
 * Mobile first. The katibu records a loan standing in a meeting, on a phone, so the phone layout is the
 * base and the desk layout is the media query — not the other way round.
