/**
 * Variant CSS: trust--client-logos-bordered-grid
 *
 * A uniform bordered grid (4x2) of faux inline-SVG wordmark logos under a short
 * "Zaufali nam" header. Every cell is an identical hairline-bordered box holding a
 * monochrome mark, so the whole wall reads tidy and even. Unlike the single inline
 * text row of names (client-logos-text-row), this is a real LOGO GRID — a portfolio
 * of brands. Logos render in --ink at low opacity and lift to full --accent on hover.
 * Header text is --ink (polarity-aware). Part of the `trust` role.
