/* === Admin Panel: Force light-mode text on form elements ===
   Admin panel uses hardcoded Tailwind classes and does NOT support
   dark theme. This prevents inherited body color from making form
   text invisible if data-theme is ever changed externally.
   Specificity: (0, 3, 1) — intentionally higher than Tailwind utilities (0, 1, 0).
   This is safe because admin forms do NOT use text color classes on inputs
   (all text-red-* in admin are on error containers <ul>/<h3>/<span>, not inputs). */
