/* v1.0.2 — Force minimum 16px font-size on text inputs and textareas
 * to prevent iOS Safari's automatic zoom-on-focus behavior.
 *
 * The bug: iOS Safari zooms into any input or textarea whose computed
 * font-size is below 16px because the OS decides the text is "too small
 * to read" and "helpfully" magnifies the field. The result is that the
 * viewport jumps when a student touches a field — exactly the "balança
 * quando vai escrever" sensation Kawe described in writing exercises.
 *
 * The fix: Setting the font-size to 16px (the threshold) tells iOS that
 * the field is already large enough, so it doesn't intervene. This
 * works WITH the browser's behavior instead of trying to override it,
 * which is why it has zero side effects. The visual size of the field
 * is unchanged in practice because the plugin's existing inputs are
 * already styled with their own font-size — this rule only matters in
 * the rare case where an input has no explicit font-size or one below
 * 16px.
 *
 * This is the ONLY change in v1.0.2. A previous v1.0.2 attempt also
 * included viewport user-scalable=no, touch-action:manipulation, and
 * overscroll-behavior:none, but those were reverted because they were
 * either ineffective (iOS Safari ignores user-scalable=no) or caused
 * the duplo-scroll keyboard bug. This release is intentionally minimal
 * — one line of CSS, one bug fixed, zero side effects expected. */
