/*
 * Homepage hero Commercial Decision Theatre
 * ------------------------------------------
 * Slice 1 of docs/site/homepage-category-brand-upgrade/.
 *
 * The existing semantic four-step rail is intentionally retained for this slice
 * so we can change the visual hierarchy without widening runtime/copy scope. The
 * rail now reads as a compact Decision Spine:
 *
 *   Company Truth + Prospect Evidence -> Commercial Alignment ->
 *   Conversation progression -> Reply-ready handoff
 *
 * Commercial Alignment is the only dominant node. The other steps remain
 * respected inputs/downstream states, but no longer read as four equal features.
 * The old equal-weight vertical dividers are intentionally retired.
