/* Universal baseline for every select/input/textarea on the site, not
   just ones inside a <form> or a specific container. Bug found: reset.css
   sets color:inherit on these (near-white text), but nothing set a
   matching dark background on ones outside .auth-shell/form/.stack-form,
   so they fell back to the browser's native white background — near-
   white text on a white native dropdown, functionally invisible. Setting
   both color AND background explicitly here, on the bare elements, is
   what actually controls a <select>'s popup list rendering in every
   major browser (color-scheme alone isn't enough once color is
   overridden). More specific per-page rules (.auth-shell input etc.)
   still win where they exist; this is just the floor everywhere else.
   Excludes type=checkbox/radio/range/color/file, which have their own
   native rendering that this would break. Wrapped in :where() so this
   carries ZERO specificity — it's a floor, not a rule that should ever
   need to out-rank a page-specific selector like .auth-shell input. */
