/* ==========================================================================
   Ampcrest Electric, portfolio demo (Storefront Digital)
   Neo-Brutalist: safety-yellow + true black + white only, thick black
   outlines, hard offset drop-shadows (no blur), sharp-cornered buttons, a
   hand-built flat bolt icon (not a sourced illustration). Real aesthetic
   touchstone: electrical warning signage / breaker-panel labeling, not a
   generic "bold brutalist SaaS" default. Archivo Black + Work Sans + Space
   Mono for numerals/labels. Hero is wordmark-led (H4, no hero photo), cards
   use a masonry span (C4) so two flagship services get a wider block, nav is
   classic left-logo/right-links (N2), closing is a flat-yellow split photo
   band (E2), not the dark inverted band every prior build used.
