+- 保存 + 提交 都是 `type="primary"` 蓝实心，视觉层级无区分。

+| 语义 | 写法 |
+| --- | --- |
+| 次要（返回/取消） | 默认（无 type）灰描边 |

+**改动文件**:
+- `business/project-apply.vue:617-651` — 主 footer + 变更 footer 都重排，`保存` 加 plain。
+- `payment/invoice-receipt-form.vue:242-252` — 保存加 plain，返回挪到保存前面。
+- `payment/invoice-application-form.vue:419-429` — 同上。
+
+**未改动（已合规）**:
+- `settlement/components/pre-settlement-editor.vue` — 默认已是「默认保存 + primary 提交」。
+- `settlement/components/transport-reconciliation-editor.vue` — 两个 plain 中间步骤 + 完成对账 实心，层级清晰。
