/* --- display type, resized for CJK ------------------------------------
   The London sizes are tuned for Barlow Condensed, which is narrow. Chinese
   glyphs are full-width and roughly square, so the same numbers overflow a
   phone: "IMPACT 概念助手，" at 54px needs ~430px of a 350px line. clamp()
   replaces the three fixed breakpoints so the headline tracks the viewport
   instead of stepping at 640/1024, which is what actually matters when the
   glyph width varies mid-line. These override the rules above by coming
   later at equal specificity. */
