  iOS Safari (all versions support -webkit-touch-callout, so this scopes to iOS/iPadOS only)
  renders regular-weight text noticeably lighter on iOS 26 than on iOS <=18, because WebKit
  changed how it resolves the system font's variable-weight default. Loading an explicit-weight
  web font above (Inter) is the primary fix; this hairline stroke is a small belt-and-suspenders
  reinforcement so body copy doesn't look washed out if a font fails to load.
