 * Asiacell LSR — shared design system.

 * Color tokens, typography, and common component classes (auth header,
 * cards, stat tiles, badges, buttons, inputs, empty/error states) used
 * across the app's pages. Link this AFTER any page-specific <style> block
 * (or before it, with page styles only overriding what's actually
 * different) — page-specific layout/domain CSS stays in each page's own
 * <style> tag; this file only holds what's meant to look identical
 * everywhere.
