/* ─── Dropdowns: one look across the whole app ───────────────────────
   The Projects field style: a quiet box (input background, hairline
   border, 6px corners) with a single chevron, the same in every browser
   (appearance: none, so iPad Safari draws what Chrome draws). The editor's
   Font / Size / Paragraph / Styles pickers copy this look in editor.css.

   The look is !important on purpose: about eighty dropdowns across the
   modules (and inline styles in JS-built forms) each carried their own
   background shorthand, padding and radius, and a `background:` shorthand
   silently removes the chevron. Modules still choose the SIZE (font-size,
   padding top/bottom/left, height, width). A dropdown that must stand out
   sets --select-bg / --select-fg / --select-border instead of fighting
   these rules (Admin Hub ticket status, Kanban history speed). */
