feat: add streaming cloud ASR, polish routing, and settings card layout

Unify Bailian/Volcengine/OpenAI realtime streaming, ABE polish routing with
fun styles, and a shared card-page Settings hierarchy; bump to 1.1 (build 32).

 ## [Unreleased]
 
+### Added
+- **True streaming cloud ASR**: Bailian, Volcengine, and OpenAI Realtime use one utterance-level WebSocket with live partials; Volcengine enables official two-pass (`enable_nonstream`) so interim text stays on-screen while definite ASR feeds polish. / **真流式云端 ASR**：百炼、火山与 OpenAI Realtime 按整句长连接推流并实时上屏；火山开启官方二遍识别（`enable_nonstream`），interim 仅上屏，definite 再送润色。
+- **Streaming ASR badge**: settings ASR provider chip shows 【流式识别】 for Bailian, Volcengine, and OpenAI. / **流式识别标签**：设置里 ASR 供应商对百炼、火山、OpenAI 显示【流式识别】。
+- **Fun polish styles**: new subcategory with Flex Guide, Corp Speak, and DiBa Logic alongside Dating Coach. / **趣味润色风格**：新增小分类，含装逼指南、大厂黑话、帝吧大神，并与直男癌拯救器同组。
+- **Xiaohongshu Sisters style**: fun polish pack that rewrites drafts into sisterly RED note body with Light/Medium/Heavy hooks (轻安利 / 种草感 / 爆款感). / **小红书集美风格**：趣味润色包，将草稿改写成姐妹向小红书笔记正文，并按轻安利 / 种草感 / 爆款感三档跳变。
+- **Delete day in History**: each day header has a Delete action with confirmation to clear that day's transcripts only (iOS and Mac). / **历史按天删除**：日期行右侧提供删除按钮，确认后仅清除当天记录（iOS 与 Mac）。
+- **Mac Settings translation target**: polish-provider section includes “Polish then translate” with the same locale picker as Home / menu bar. / **Mac 设置翻译目标**：润色（LLM）分区新增「润色后翻译」，与首页 / 菜单栏同一套目标语言选择。
+
+### Changed
+- **Two-tier short polish skip**: ultra-short (≤4 CJK) still skips the LLM; 5–10 CJK now skips only low-value acks/closings (e.g. “好的我知道了”), while questions and contentful shorts still polish. / **两级短句跳过润色**：≤4 字仍跳过 LLM；5–10 字仅对低价值确认/收束语跳过（如「好的我知道了」），问句与有内容短句仍走润色。
+- **ABE polish routing**: fun styles and daily chat use a local information-density gate, prompt hard-brakes, and style-specific degrade (e.g. DiBa without an opponent quote falls back to chat cleanup) without a second LLM call. / **ABE 润色路由**：趣味风格与日常聊天增加本地信息密度闸、提示词硬刹车与风格专属降级（如帝吧无对方原话时降级日常清理），不增加第二次 LLM 调用。
+- **Practical polish prompts**: Light Clean / Structured / Formal / Daily Chat share a “transcript-only, not a chatbot” boundary; Structured gains active itemization, light semantic reorder, and paragraphing hard rules inspired by high-readability polish patterns. / **实用润色提示词**：轻度清理 / 清晰结构 / 正式表达 / 日常聊天统一「只整理转写、非聊天助手」边界；清晰结构加强积极分项、轻度语义重排与分段硬规则，提升长口述可读性。
+- **Settings hierarchy**: voice-session options join Daily, while ASR and LLM configuration links sit directly below the transcription-mode choices; General and About remain secondary pages. / **设置层级**：语音会话选项并入「日常」，ASR 与 LLM 配置入口紧跟转写模式选择；通用与关于保留为二级页。
+- **Transcription option rows**: local and cloud choices now use the same text-first list-row style as the rest of Settings, without leading icons. / **转写选项行**：本地与云端选项移除前置图标，统一采用设置页的文字优先列表样式。
+- **Simplified style cards and summaries**: polish-style cards drop decorative badges, and speech-configuration summaries show only the active engine or provider/model without redundant status prefixes. / **简化风格卡与摘要**：润色风格卡移除装饰图标；语音配置摘要仅显示引擎或服务商/模型，不再附加冗余状态前缀。
+- **Mac polish style grid**: cards drop decorative icons and use a denser adaptive grid (about three columns at the default window; two when narrower, four+ when wider). / **Mac 润色风格网格**：卡片去掉装饰图标，并以更密的自适应网格排布（默认窗口约三列；变窄两列、变宽四列及以上）。
+- **OpenAI ASR default**: cloud OpenAI ASR defaults to `gpt-realtime-whisper` for streaming; batch transcription remains the fallback. / **OpenAI ASR 默认**：云端 OpenAI ASR 默认 `gpt-realtime-whisper` 走流式；批处理转写仍作降级。
+- **Dating Coach prompt**: spoken WeChat first with clever lines only as seasoning; refreshed examples to reduce copywriting AI tone. / **直男癌拯救器提示词**：以口语微信为主、巧思仅作点缀；刷新示例以降低文案式 AI 腔。
+- **Unified card-page layout**: Settings, polish styles, and related detail pages now share 20-point page margins, section labels, and card chrome. / **统一卡片页面布局**：设置、润色风格及相关详情页共用 20 点页面留白、分组标题和卡片外观。
+
+### Fixed
+- **Daily-chat short replies**: chat polish forbids interlocutor-style continuations on ultra-short drafts (e.g. “嗯” no longer becomes “嗯，我在呢”). / **日常聊天短句接话**：日常润色禁止对极短草稿做对方口吻续写（如「嗯」不再变成「嗯，我在呢」）。
+- **Card corner consistency**: the seven-day chart and shared usage cards now use the same continuous 20-point corners as the other Home cards; shared Settings cards also clip child backgrounds to their border shape. / **卡片圆角一致性**：最近 7 天图表及共享统计卡改用与首页其他卡片一致的连续 20 点圆角；共享设置卡片也会将子视图背景裁切到边框形状。
+- **PiP mic spin-up drop**: on record press, open capture and the utterance gate before waiting for audio proof, and keep ~3 s of idle preroll so speech during mic warm-up is not discarded. / **PiP 开麦丢音**：按下录音后先启动采集并打开 utterance gate，再等待音频证明；空闲 preroll 约 3 秒，避免麦克风预热期间的语音被丢掉。
+- **Empty preMerge wipe**: final-chunk preMerge that returns empty text no longer removes a prior good segment; ASR pipeline failures also recover via partial snapshot instead of clearing it. / **空 preMerge 抹字**：末块 preMerge 若识别为空，不再删除已有有效片段；流水线失败时改用 partial 快照恢复，而不再清空兜底。
+- **History day label alignment**: date headers line up with the history card's left edge like Settings section labels. / **历史日期对齐**：日期标题与下方卡片左边缘对齐，与设置页分组标题一致。

-            - **Light（暖而不撩）**：允许为消除盘问、说教、命令、敷衍、推责或压迫感而改写清楚的措辞。先接住感受，保留用户口吻；不主动新增暧昧、调侃或关系推进。
-            - **Medium（温度与趣味）**：在 Light 基础上，可加入一处具体观察、亲和幽默、自然分享、跟进问题或克制的偏好信号，让人更想回应。暧昧必须轻、可退、可按字面理解。
-            - **Heavy（主动而明确）**：在原文已有好感或邀约意图，且语境没有拒绝、冷淡、权力不对等等风险时，可更主动地表达欣赏、想念、期待或约会意图。浪漫张力可以更强，但直接度应上升、猜谜应减少；仍不得擅自表白、许诺或升级身体和性边界。
-
-            # 关系许可闸
-            - 没有恋爱信号：即使 Heavy 也只增强温度、趣味和表达力，不主动制造暧昧。
-            - 原文已有单向好感：可以表达己方感受或邀请，但必须保留真实拒绝空间。
-            - 上文显示双方已有稳定玩笑、追问或暧昧：可按力度增强俏皮、画面感和期待。
-            - 对方短答、回避、改话题、拒绝、不适，或原文在催回复、讨价还价：任何力度都立即降为礼貌、直接、低压力的表达，不把冷淡解释成欲擒故纵。
-            - 涉及上下级、师生、医疗照护等权力不对等，或酒精、疾病、悲伤等脆弱状态：锁定 Light，不推进关系。
-
-            # 改写方法
-            先识别原文是在开启话题、回应情绪、关心、赞美、邀约、想念、道歉、冲突、确认关系还是接受拒绝，再做最少但最有效的改动：
-            1. **评判改为回应**：先体现听懂对方的事实或感受，再分享看法；对方未求建议时，不用「你应该」「早听我的」开头。
-            2. **索取改为表达**：把「在吗」「想我没」「怎么不回」改成带有自身信息、感受或来意的表达，不让对方独自承担开启和维持对话。
-            3. **控制改为选择**：关心、建议和邀约要明确但不命令；不替对方决定，不先斩后奏，不用请客、付出或失望换取答应。
-            4. **空话改为具体**：只根据原文或上文已有细节赞美选择、能力、气质、努力或给人的感受；没有细节时宁可朴素，不硬编赞美。
-            5. **提问体现倾听**：优先追问对方刚说过的细节、感受或意义；一条短消息最多一个主要问题，禁止查户口式连问。
-            6. **幽默保持亲和**：可用轻自嘲、共同笑点、反差或双关；不拿对方的外貌、能力、身份、性史、家庭或创伤开玩笑。
-            7. **自我披露保持对等**：只分享与当前话题和关系深度相称的一小步，不倾倒创伤，不抢走对话中心。
-            8. **道歉承担责任**：说清具体行为与影响，不用「但」「如果你觉得」「不是故意的」撤回责任，不索取立即原谅。
-            9. **冲突描述具体**：用具体事件、感受、需要和请求替代「你总是」「你从来不」；需要暂停时说明原因和返回时间。
-            10. **拒绝干净收束**：接受「不」「算了」「只是朋友」及同义表达，不追问、不谈判、不贬低、不换平台纠缠。
-
-            # 长度与风格
-            - 保留用户可辨认的词汇、直接程度和个性；这是润色，不是替用户扮演另一个人格。
-            - 15 个字以内的短句可增加一个短分句以补足来意、温度或退路；Medium 最多一个互动钩子；Heavy 最多两个自然语言节拍。
-            - 较长消息贴近原有信息量，不扩写成长段、情书、鸡汤或连续追问；普通聊天不分标题、不列清单。
-            - 自信但不自恋，主动但不强迫，幽默但不冒犯，暧昧但不露骨。
-            - 使用当代自然口语，不堆形容词、排比、网络土味情话或故作深情的比喻。
-            - 不凭空使用「宝贝」「美女」「乖」等亲昵称呼，不主动新增 emoji。
-
-            # 安全边界
-            禁止 PUA、忽冷忽热、故意延迟回复、贬低后安抚、卖惨绑架、竞争或嫉妒诱导、试探服从、未经同意定义关系、物化、露骨性暗示、骚扰，以及利用年龄、权力、酒精或脆弱状态推进关系。暧昧不能代替明确同意；涉及身体、性、关系确认或边界时，必须使用清楚、可拒绝的表达。

+            **意图守恒，措辞可整句重写。** 保留原文交际目的（关心、邀约、赞美、想念、道歉、开启话题等），不保留伤人、无聊或直男式壳子。禁止编造共同经历、对方说过的话、具体约会细节、关系承诺或未表达的事实。
+            遮住力度标签后，Light / Medium / Heavy 仍应明显区分；不要做近义微调。
+
+            # 语感：口语为主，巧思点缀
+            - 主体是当代自然口语：短、顺口、有态度；可读、可直接发送。
+            - 允许偶尔一个小比喻、反差或俏皮收束，但一条消息最多一处；不要句句都在玩花样。
+            - 过浓（应避免当默认）：精致隐喻工厂（现实绑架、脑内弹窗、破坏专注力等）、破折号金句、工整对仗、每条必带钩子问句、小红书/恋爱博主腔。
+            - 过淡（也应避免）：干巴通知、纯事务安排、去掉所有趣味后只剩礼貌。
+

+            - **Light（加戏）**：去掉盘问/说教/压迫，加一点态度或轻幽默，好玩、好接；几乎不暧昧。
+            - **Medium（会撩）**：在加戏之上带可读暧昧（偏好、拉近、可退的俏皮）；不露骨。
+            - **Heavy（更挑逗）**：比 Medium 更大胆的试探或黏人玩笑；仍是挑逗而非色情，必须保留拒绝空间。
+

+            - 对方短答、回避、改话题、明确拒绝、不适，或原文在催回复、讨价还价、道德绑架：任何力度都改为礼貌、干净、低压力收束；禁止继续撩，不把冷淡当欲擒故纵。

+            - 道歉与冲突：以承担责任、具体请求为主；不要用挑逗逃避责任。
+
+            # 改写要点
+            1. 干巴变有态度：先给自己的状态或来意，再问或邀。
+            2. 命令变选择：关心与邀约明确但不强迫，留退路。

+
+            # 长度
+            - 仍是可直接发送的 1–2 句聊天；短句可扩到约 1.5–2 倍信息量，不写小作文或情书。

+            Heavy：集美们真诚避雷⚠️
+            排了好久才吃上，结果味道平平，期待落差有点大。
