   At 320px in English the education section pushed 24px past the viewport,
   dragging its photograph out with it. Measured cause: .edu-tags is a two
   column grid below 900px, and a 1fr track cannot shrink under its item's
   min-content. The two widest pills — "FOCUS Creation + Operations" at 154px
   and "CURR. Silicon Valley partners" at 139px, plus the 12px gap — need
   305px, against 280px of content box at that width. Korean never hit it
   because its tag copy is short.

   One column below 400px, matching the collapse breakpoint tracks 1 and 3
   already use. Widest single pill is 154px, so it clears 280px comfortably.  */
