/**
 * Variant CSS: offer--single-side-accent-rule
 * Layer 2 — Path B universal offer variant (authored 2026-06-10).
 *
 * Concept: ONE flagship service as a LEFT-RULE editorial block. A vertical accent
 * bar runs down the left edge of the content; alongside it, in the left axis, sit
 * the kicker, an oversized title, the description, an optional price and one CTA.
 * Generous whitespace, no card and no closed border — a left-margin "marginalia"
 * paragraph, not a framed panel.
 * Built for Element Count: 1 (the rebuild keeps exactly one service).
 *
 * Differentiator vs sibling EC=1 offer variants:
 *   - bordered-feature-panel: a fully ENCLOSED panel with corner ticks + price.
 *   - editorial-manifesto: chrome-less, a HUGE statement with a dot-separated row.
 *   - single-split-panel: two columns with a solid accent colour panel aside.
 *   - solo-feature-statement: a card with a top accent rule + icon, centred-ish.
 *   THIS one: a single thin VERTICAL accent rule beside left-aligned type — one
 *   line carries the whole signal; the block is open on three sides.
 *
 * Colour intent: text on the section --background, --text-primary / --text-secondary.
 * The vertical rule + the <em> keyword use --accent. Nothing is centred (left axis),
 * so the A8/A9 left-shift rule does not apply.
 *
 * area-1-* tokens: title, desc, price. Section: kicker, cta.
