/*
 * Velo Prime — Ledger theme kit, "developer-tool" restyle.
 *
 * The :root block below is this business's palette and type. Per a
 * founder-requested color/texture correction: the ink role is a neutral
 * charcoal/near-black (no brown cast), the graph-paper grid texture that
 * used to live in the ink bands has been removed entirely (clean solid
 * dark fill), and the accent role is green — the single accent color
 * used for CTAs, the eyebrow marker, and emphasis rules.
 *
 * Contrast (WCAG AA 4.5:1 floor): ink-on-canvas, ink-on-surface,
 * ink-on-section-tint, accent-text-on-surface/canvas, and the CTA
 * pairing (canvas-on-ink / white-on-accent) all clear the floor with
 * this palette's intended role usage.
 *
 * "Techy / developer-tool" direction, achieved entirely within the
 * assigned palette and the two assigned typefaces (no new font family is
 * introduced anywhere below):
 *   - Sharp edges: --zb-radius is 0 everywhere (buttons, photo frames,
 *     cards, inputs) instead of a soft rounded corner.
 *   - Ink (the dominant-contrast role) fills the hero, the closing CTA,
 *     and the footer — a dark anchor at the top, middle-close, and
 *     bottom of the page — as a clean, untextured solid fill.
 *   - Headline type leans on its heaviest weights with tight, uppercase
 *     tracking for labels — reads structured/technical without
 *     substituting a monospace face the palette didn't provide.
