/**
 * CF Value Cards — five-mode framework per CF_MODULE_GUIDE §8.
 *
 * Modes (chosen for the corporate-security executive lens — Ontic,
 * Dragonfly, Seerist, ASIS, Control Risks, International SOS):
 *
 *   .cf-value-cards--light-sky    Briefing-grade default (calm, credible)
 *   .cf-value-cards--light-slate  Analytical / operational
 *   .cf-value-cards--light-paper  Editorial / long-form (white bg, navy ink)
 *   .cf-value-cards--light-mint   Positive outcome (use sparingly)
 *   .cf-value-cards--dark-navy    Brand authority (one anchor per page)
 *   .cf-value-cards--dark-ops     GSOC / command center (amber accent)
 *
 * Each mode defines its own palette via CSS custom properties; the rest
 * of the styles read from those properties so the same markup serves
 * all five.
 *
 * Default values pulled from cf_core/brand. The lifted-navy card-bg and
 * white card-bg in light modes are module-local.
 *
 * Icon SVGs should use stroke="currentColor" / fill="currentColor" — the
 * .cf-value-cards__icon container's `color` is set to --cfvc-icon, so
 * the icon adopts that color automatically.

/* ── Phone layout: horizontal feature-row pattern ───────────────────────
   Below 560px the 4-up grid collapses to 1 column. The desktop
   "centered card with big icon on top" treatment then reads as four
   ceremonious tiles — slow to scan and icon-dominant. Restructure
   each card into a row: icon left (44px), heading + description
   right, left-aligned. Drop the per-card border / rounded box and
   use hairline rules between rows instead (matches cf_services_strip
   mobile treatment — once content is in row layout, card boxes feel
   redundant and dividers read cleaner). Tighten section + header
   padding so the whole block doesn't waste vertical real estate on
   phones; bump description size to 15px so it stays readable in dim
   conditions (airline cabins, evening commutes — the conditions in
   which a CSO actually reads on a phone). Desktop is untouched.    */
