/**
 * DocuPOW — Shared Flow-page styles (the /flows/* vertical pages built in
 * batch 2: accounts-payable, invoice-processing, three-way-match,
 * procure-to-pay, order-intake, claims-processing, kyc-onboarding).
 *
 * ONE stylesheet, scoped under .page-flow-vertical (BEM), enqueued for all of
 * those templates. Global chrome/container/buttons/links/scroll-reveal come
 * from main.css. Structure: light hero -> gray stage-chain (white numbered
 * step cards) -> obsidian systems-handoff band -> white final CTA (with the
 * Flows Library link). NO page JS. Tokens only (zero new hexes).
 *
 * Contrast: hero eyebrow techblue (4.54:1 on white, AA); h1 + section h2 indigo;
 * step labels ink; body var(--text-muted); ALL techblue links sit on WHITE
 * surfaces (step cards + the white CTA), never on --gray, with hover-underline.
 * Obsidian handoff band: white heading, --text-muted-dark body (7.58:1, AA),
 * light focus halo. Card hover-lift via `translate` (disabled under reduce).
