/*
 * AllinAI Begin Child - R0.6 home + core styles.
 *
 * Builds on R0.5.2 (home-r05.css). Reuses R0.5.2 color variables and
 * hero shell. Adds the six R0.6 homepage sections, the five core page
 * renderers, and the six category landing layouts.
 *
 * No animations. No keyframes. No !important. Touch targets >= 44px.
 *
 * Topology map (avoid 1px cliffs):
 *   >= 1152px: 3-column category grid; 3-column path on desktop only.
 *   769 - 1151px: 2-column category grid; 1-column path.
 *   441 - 768px: 1-column category grid; 1-column path; nav collapses.
 *   <= 440px: 1-column everything; nav is toggle-only.
