/* OPSIS marketing site.
 *
 * Brand tokens come from packages/shared/src/tokens.ts. One accent (indigo)
 * carries every primary action; crimson is reserved for the wordmark dot and
 * the hero accent so the page reads as one system. Spacing is an 8px scale,
 * radii are 12/16, and every text container is allowed to wrap anywhere so a
 * long LGA name can never push the page wider than the screen. */
