/*
 * hax-challenges-empty.css
 *
 * Empty-Challenges "starting board" 1-2-3 onboarding card (operator decision 2026-05-29).
 * Only renders for viewers who have never had a challenge — see ChallengesOnboardingState
 * + ChallengesQueue.razor for the gating. Returning viewers see the standard More-options
 * empty state which uses inline MudBlazor utilities and needs no extra CSS.
 *
 * Scope: every rule is anchored under .hax-onboarding so this file can't bleed onto the
 * standard empty-state copy or any other surface.
 *
 * Mobile (≤720px): the three step cards stack vertically full-width. Step-num + glyph
 * shift to a row at the top of each card so the card stays compact when stacked. Desktop
 * keeps the three-up row with even widths via grid-template-columns: repeat(3, 1fr).
