/**
 * Shared mixin for the client stepper steps.
 *
 * When the per-step `readOnly` flag is on, the host calls `form.disable()` which
 * cascades Material's default `~0.38 opacity` onto every outlined input,
 * select, checkbox and label. Visually it reads as "blurry". This mixin keeps
 * the disabled affordances (no caret, no border highlight on focus, no
 * pointer cursor on selects) but restores crisp colour + weight so the saved
 * values stay legible.
 *
 * Usage in a step component's .scss:
 *
 *   @use '../stepper-readonly-overrides' as readonly;
 *
 *   :host {
 *     @include readonly.readonly-form-overrides;
 *   }
