/* Hallmark · redesign (in-place) · pre-emit critique: P4 H4 E4 S4 R4 V4
     * Recolored .ab-fields/.ab-why/.ab-partners off the old warm-linen
     * palette (#F2E8D4/#FDFAF2/warm-brown text) onto the site's locked
     * cool blue-ochre tokens — this page had drifted onto a different
     * hue family than Landing/CorporateEvents/TripBuilder. Also removed
     * the italic .ab-why-title (a full italicized heading, not inline
     * emphasis — anti-pattern per typography purity).
