/*!
 * Client Brief System — Shared stylesheet
 * -----------------------------------------------------------------------
 * NOT one of the 5 named modules in the architecture doc — added because
 * the UX requirements (progress indicator, large touch targets, clear
 * selected states, mobile-first layout) cannot be met with JS alone
 * without either inline styles scattered across three pages or a shared
 * stylesheet. A shared stylesheet is the smaller, more maintainable
 * option, and it's the one used here. Documented per the instruction to
 * flag any deviation from the five-module list.
 *
 * Every value below is a REUSE of an existing Abhigyan design token —
 * nothing here introduces a new colour or font. Confirmed against the
 * live site's :root custom properties (see CLIENT_BRIEF_SYSTEM_AUDIT.md,
 * Section B): --ink, --ink-deep, --chalk, --chalk-dim, --amber,
 * --amber-deep, --line-soft, Space Grotesk / Inter / IBM Plex Mono, and
 * the [data-theme="light"] override mechanism.
 *
 * This file assumes those custom properties are already defined on the
 * page (they are, on every existing Abhigyan page) — it does not redefine
 * them, only consumes them.
