/* :where(...) keeps this whole selector at zero specificity, same

   e.g. a fixed width for compact inline forms) still wins, exactly
   like it did before this rule existed. Without :where(), the
   :not()s below add enough specificity to silently beat those
   page-level overrides, which is a real regression (found live:
   alarm-rules.html's fields went full-width while its <select>s
   stayed at the page's intended 220px).
   :not([type=checkbox]):not([type=radio]) rather than an explicit
   input[type=text] list -- a plain <input> with no type attribute
   at all (implicitly type=text) is common across these pages and
   was NOT matched by an input[type=text] attribute selector, since
   attribute selectors require the attribute to actually be present
