/* The select box itself picks up --input-bg/--text above, but the native
   dropdown popup (the open option list) is drawn by the OS, not by us.
   On Windows/Chromium in particular, the popup background stays white no
   matter what CSS says (color-scheme and option background are both
   ignored there) — but our light --text color WAS still being applied to
   the option text, which is what actually made it unreadable: light text
   on a background we can't turn dark. Forcing dark, high-contrast text
   here (rather than fighting the unstylable white background) is what
   actually fixes it, even though it means this one native popup doesn't
   match the app's dark theme. */
