/*
 * shajara.sa: the pages the stores and the invitation links need (G3.6, G9.5).
 *
 * Every value is the app's: the design handoff's tokens (`assets/shajara.css`) in light, and
 * `lib/colors.dark.ts` in dark, where the shadows go black as R6 there says. The hero is the
 * welcome screen's (`app/(auth)/index.tsx`, 01 Auth frame A): an indigo plane pinned to its
 * light values in both themes, with the logotype in parchment, as the brand brief locks it.
 * The code field is the join screen's (02 Onboarding frame F), the prose card the legal
 * screen's (`components/support/pieces.tsx`). No borders between sections (the No-Line rule):
 * tone, space and soft shadows.
