/* چتر آبی — Status & Announcements
   Design concept: a weather log behind glass. The umbrella brand becomes
   a literal sky: clear (all good), cloudy (planned maintenance),
   stormy (incidents / security advisories). The hero is a slow drifting
   sky gradient; the feed is a vertical timeline reading top-to-bottom,
   right-aligned for RTL, because order here carries real information. */
