/*
 * rh-csv-tabellen-hub — display-only category hub stylesheet.
 * Follows the rh-address-hub v2.0.3 category-hub design standard (see
 * plugins/rh-address-hub/README.md §15). v1.1.0 brings this hub into
 * alignment with that standard.
 *
 * Inherits the shared .rh-tool chrome from rh-tools-core. Local rules
 * own only:
 *   1. header spacing (margin-bottom = 0; section rhythm owns the gap)
 *   2. explicit section rhythm — every top-level section/nav carries
 *      `margin-top: 2rem` at desktop (mobile 1.5rem)
 *   3. section-title rhythm (no top margin)
 *   4. card grid — 4×2 at ≥900 px, 2×4 at 720–900 px, 1×8 at ≤720 px
 *      (curated 8-card primary inventory; no orphan layout at any
 *      common container width)
 *   5. card visual treatment (bg, hover, focus-visible) — CTA arrow
 *      moves 2 px on card hover/focus
 *   6. empty notice
 *   7. explanatory notes section — "Was diese Werkzeuge können" /
 *      "Was diese Werkzeuge nicht tun"
 *   8. trust panel — "Datenschutz & Verarbeitung" 3-up grid
 *   9. guide cards with `Leitfaden` chip — visually distinct from
 *      tool cards
 *  10. siblings — cross-hub exit navigation pill chips
 *  11. FAQ — open-state segmentation
 *  12. mobile breakpoints (782 px / 720 px)
 *
 * Rules for future edits:
 *   - All selectors scoped under .rh-csv-tabellen-hub.
 *   - No global selectors, no unscoped .rh-tool* rules.
 *   - No @import, no url(), no remote fonts, no icon libraries, no CDN.
 *   - No JavaScript references — display-only.
 *   - Notes modules stay visually distinct from clickable cards.
 *   - No compliance/badge styling. No red alarm blocks.
 *   - Curated fixed-count allowlist (8 cards) → explicit grid columns
 *     at desktop + tablet, NOT auto-fit; auto-fit would orphan at
 *     3-column widths.
 *   - CTA arrow in aria-hidden span with `transform: translateX(2px)`
 *     on parent link hover/focus. No keyframes.

 * inventory (1.1.1 tightening of the v1.1.0 4×2 grid).
 *
 *   ≥1180 px:  4×2 grid (wide desktop only — enough width for 4-up cards
 *              with the new title/desc lengths)
 *    900–1179: 3×3 grid with one wider card (or 3 + 3 + 2) — avoids the
 *              cramped 4-up layout at mid-desktop widths
 *    540–900:  2×4 grid (tablet baseline)
 *    ≤540 px:  1×8 stack (mobile, handled by the 720 px breakpoint at
 *              the bottom of this file)
 *
 * Auto-fit would orphan unpredictably at intermediate widths; explicit
 * graduated breakpoints keep the card layout stable and readable. The
 * v1.1.0 single 4-col-at-≥900 rule was too aggressive for narrow desktop
 * containers (~900–1100 px) where 4 cards became visually cramped.
