/**
 * company: cube one GmbH
 * name: cube-group.css
 * author: Thomas Schäfer
 * created: 16.08.2026
 * change log: 07.09.2026 – Thomas Schäfer – Group hero lead uses full text
 *             primary brightness (removed 0.92 opacity wash).
 * change log: 05.09.2026 – Thomas Schäfer – Group hero drops the landing-page
 *             min-height and bottom-aligned copy so it matches the shared
 *             theme-banner padding and headline scale.
 * change log: 04.09.2026 – Thomas Schäfer – Dropped the 74ch cap on
 *             .group-article .article-body: the article grid track now carries
 *             the reading measure, so the cap only kept the copy 4px short of
 *             the headings beside it.
 * change log: 25.08.2026 – Thomas Schäfer – Homepage group teaser cards
 *             (.group-home__brand) use the values-duo glow pattern in orange,
 *             cube care berry and cube hub lime.
 * change log: 16.08.2026 – Added the bilingual cube group brand system, homepage teaser and article styles.
 *             16.08.2026 – Thomas Schäfer – Keep the white label on the dark CARE primary button after the global .btn-primary switched to a near-black label.
 *             04.09.2026 – Thomas Schäfer – CARE and HUB primary buttons follow the global lit-from-above gradient in their own hue and retune the cast shadow via --btn-cast; removed the ::after rule for the deleted idle pulse.
 *             04.09.2026 – Thomas Schäfer – Brand cards move the hover edge of the now globally defined .btn-secondary to berry and lime via --btn-edge.
 *             16.08.2026 – Thomas Schäfer – Integrated the official cube care logo and magenta brand accent.
 *             20.08.2026 – Thomas Schäfer – CUBE HUB rebrand: official lime accent (--hub-accent) for the hub brand card (timeline dot, hover border, promise bullets, index, primary button) and the white wordmark logo in the visual pill.
 *             20.08.2026 – Thomas Schäfer – Brand headings use official white wordmark logos; logo overlay pills on the visuals removed.
 *             21.08.2026 – Thomas Schäfer – Homepage brand cards use the three avatar motifs with offset wordmarks in diagonal CUBE frames.
 *             21.08.2026 – Thomas Schäfer – Group teaser subline renders on a single line from 1200px up (global .section-sub measure lifted); narrower viewports keep wrapping.
 *             21.08.2026 – Thomas Schäfer – Rebuilt homepage group cards as a resilient vertical 16:9 media-and-copy layout with contained logo badges and equal-height responsive cards.
 *             21.08.2026 – Thomas Schäfer – Added brand-colour hover frames and news-style read-more cues to the homepage group cards.
 *             21.08.2026 – Thomas Schäfer – Lightened the group hero and homepage banner veils while retaining readable text contrast.
 *             22.08.2026 – Thomas Schäfer – Homepage group heading and lead now share the full section-container width at every breakpoint.
 *             29.08.2026 – Thomas Schäfer – Replaced the broad 0.88 group-hero
 *             blackout with a localized left text scrim and light frame wash.
 *             29.08.2026 – Thomas Schäfer – Group hero uses the shared flat
 *             banner veil; no darker centre or left text scrim.
