/* ApacheWatch marketing site — shared stylesheet
   Adapted from the ORDSwatch/NGINXwatch sibling products' stylesheet;
   only the accent color changed (orange, matching ApacheWatch's own
   existing app accent, --e05b2b) — layout classes and structure are
   otherwise identical across all three products' marketing sites.
   No build step, no external fonts/icons. System font stack only. */
