/* ---------------------------------------------------------------------------
 * Companion products — "Other Great Tools"
 *
 * A logo-led editorial showcase: a quiet tab rail in the carousel's idiom, then
 * one airy split per product with the real app icon beside its story. No nested
 * cards; hairlines and the shell width do the separating. Every colour routes
 * through the site tokens in css/site.css, so light and dark both follow.
 * --companion-accent is set inline per product from a validated hex value and
 * falls back to the site accent.
