LRC-LIB-CATALOG-IMPORT: reconcile import with current main

Preserve upstream phased progress and typed cancellation alongside deduplicated original probing and offline import results. Adapt result-dialog tests to the consolidated progress helper. Preserve both sets of locale messages and current progress-document entries.

Validated the combined tree with all eight cargo xtask ci gates (3,462 passing test executions), fresh 30k import and saved-record checks, duplicate-free same-session and reopened reimports, and inspected headless screenshots. Astra integration review findings are addressed.

Generated with Codex.

-## Built for agents
-
-LightCraft 裡的每一個選單項目、滑桿、筆刷筆觸、裁切控點與按鍵，都是一個擁有穩定 ID 與
-JSON 參數的**指令**。介面、鍵盤、CLI、JSON-lines 控制通道與一個 **MCP 伺服器**全都透過同一個入口分派。
-代理可以挑片、顯影、為天空加上遮色片並匯出，而且能*看到*結果。
-
-```sh
-lightcraft --control 7980 ~/Pictures/trip
-```
-```jsonc
-{"method": "engine.execute", "params": {"command": "photo.flag",  "params": {"flag": "pick"}}}
-{"method": "engine.execute", "params": {"command": "develop.set", "params": {"values": {"light.highlights": -45, "light.shadows": 38}}}}

-
-- **指令註冊表。** `engine.commands` 列出可用的指令；`develop.controls` 列出每個滑桿的範圍、
-  預設值與目前值。
-- **MCP 伺服器。** `lightcraft-cli mcp` 把指令註冊表開放給 Claude（或任何 MCP 用戶端），
-  同時提供匯入、查詢、顯影、遮色片、算繪（以影像回傳）與匯出的輔助工具。它可以無介面執行，也可以附掛
-  到正在執行的應用程式上，支援截圖、點擊與手勢。詳見 [docs/mcp.md](docs/mcp.md)。
-
-  ```sh
-  cargo build --release -p lightcraft-cli
-  claude mcp add lightcraft -- "$PWD/target/release/lightcraft-cli" mcp ~/Pictures/shoot          # 無介面
-  claude mcp add lightcraft-app -- "$PWD/target/release/lightcraft-cli" mcp --connect 127.0.0.1:7980  # 操作執行中的應用程式
-  ```
-- **可腳本化的 CLI：** `lightcraft-cli run --import in.dng develop.set control=light.exposure value=0.7 app.export
-  path=out.jpg longEdge=2048` 可執行任意指令鏈（無介面、對已儲存的照片庫，或對執行中的應用程式），
-  每條指令印出一行 JSON 結果；`lightcraft-cli render in.dng -o out.jpg --set light.exposure=0.7 --preset …`。
-- **一切皆可復原**，包括代理的操作：一次滑桿拖曳（或腳本中一連串的更新）算一步復原。
-- **縮圖目錄（原生應用程式／CLI）：** 選取照片，然後 **檔案 → 縮圖目錄 PDF…**。可選擇 A4 或 Letter、橫向、
-  列數與欄數，以及檔名圖說；儲存分頁 PDF，再用你的 PDF 檢視器列印。匯出會套用目前的編輯，每張照片完整放入
-  而不再次裁切，以 150 dpi 和 sRGB 算繪。背景匯出支援取消，並保護原始檔案與 XMP 附屬檔案。從 CLI 呼叫：
-
-  ```sh
-  lightcraft-cli run --import ~/Pictures/shoot library.selectAll export.contactSheet path=Contact.pdf paper=a4 columns=3 rows=4 captions=true
-  ```
-
-  `export.contactSheet` 也接受明確的 `ids`、`landscape=true` 和 `paper=letter`。只有在整份 PDF 成功產生之後，
-  它才會取代既有的輸出檔案。限制：1,000 張照片、100 頁、256 MiB；圖說使用與浮水印相同的字型涵蓋範圍來點陣化
-  （CJK 文字需要 craft-fonts），過長的名稱會在中間省略。
-  這是一套縮圖目錄工作流程，
-  不是印表機驅動程式或自訂拼版編輯器。
-- **列印版面（原生應用程式／CLI）：** **檔案 → 列印…** 會開啟「列印」模組的版面編輯器：單張照片、
-  縮圖目錄、相片包（自動版面會把格子排進頁面）與自訂相片包（拖曳並調整格子大小、堆疊順序、對齊格子或
-  格線），縮放填滿／旋轉以符合、相片邊框與內框線，紙張尺寸從 4 × 6 到 13 × 19 以及 A3 到 A5 或自訂，
-  邊界、以英吋／公分／公釐／點為單位的尺規、頁面背景、72–720 ppi，以及已儲存的範本。**列印為 PDF…**
-  會在背景算繪。一切都是 `print.*` 指令
-  （`print.get`、`print.set`、`print.cell.add`、`print.layout.autoLayout`、`print.exportPdf`、
-  `print.template.save`……），所以 CLI 和 MCP 也能操作它：
-
-  ```sh
-  lightcraft-cli run --import ~/Pictures/shoot print.set 'layout={"style":"picturePackage","page":{"paper":"8x10"}}' \
-      print.cell.add width=5 height=7 print.cell.add width=2.5 height=3.5 print.layout.autoLayout print.exportPdf path=Package.pdf
-  ```
-
-  印表機色彩管理與頁面疊加層（身分標識、浮水印、頁碼）目前還沒有。
-- **每個控制項都可定址**（`ui.widgets`）且可依名稱點擊，所以代理操作的是真實介面，而不是走旁門。
-- 本 README 中的截圖全部由 [`docs/showcase/`](docs/showcase/) 腳本全自動產生。
-  協定參考：[docs/control-protocol.md](docs/control-protocol.md)。

-- **場景參考與寬色域。** 內部使用線性 Rec.2020 浮點、Bradford 色彩適應的白平衡、以色域映射取代裁剪，
-  raw 走底片式肩部曲線，未經改動的 JPEG 則採像素級直通。
-- **解析度無關的編輯。** 半徑與筆刷大小都相對於影像，所以 400 px 的預覽、你的 5K 顯示器和 60 MP 的匯出
-  看起來完全一致。
-- **GPU 加速，與 CPU 結果一致。** 整條顯影管線都以 wgpu 計算核心執行（Metal／Vulkan／DX12），
-  並與 CPU 管線比對到 1/255 以內的誤差。在 24 MP 的 raw 上（Apple M4 Pro）：一次滑桿更新約 4 ms 重新算繪，
-  冷啟動的 2.5 MP 放大檢視約 30 ms，全尺寸匯出約 0.3 秒（含平行 JPEG 編碼）。
-  沒有 GPU 時，同一條管線會在所有 CPU 核心上執行，只重做受滑桿影響的那些階段。批次匯出會同時算繪多張照片，
-  所以一張的解碼與編碼能和另一張的算繪重疊。
-- **即時挑片。** 開啟一張 raw 會在約 0.1 秒內顯示其內嵌的相機預覽或快取算繪結果，完整算繪隨後跟上
-  （24 MP 約 0.2–0.5 秒）。上一張與下一張會在背景準備好，因此瀏覽整批照片時每張約 50 ms。
-- **背景算繪。** 一個工作執行緒池在 UI 執行緒之外算繪放大檢視、編輯前／後對比與每一個可見縮圖：
-  拖曳時用草稿品質，放開後以完整品質算繪。
-- **本機優先。** 沒有帳號、沒有雲端、沒有遙測、沒有訂閱。你的目錄是一份只會附加寫入、可讀的操作紀錄，
-  可以比對差異、備份或重播。

-## Feature status
-
-LightCraft 還很年輕，而且進展飛快：**Alpha 階段**。**老實說，我們目前的進度是**（細節見[路線圖](ROADMAP.md)和
-[docs/target-app-parity.md](docs/target-app-parity.md)）：
-
-- **依功能數量計算，約達 Lightroom 的 81%**（核心功能 98%），逐行記錄在
-  [docs/parity-checklist.md](docs/parity-checklist.md)。
-- **作為日常取代 Lightroom 的工具，整體產品更接近 61%，對一般全職攝影師約 51%，一般休閒用途約 65%。**
-  在單機上處理 JPEG/DNG，以及大多數 Sony／Panasonic／
-  Fujifilm／Nikon／較舊款 Canon 的 raw 都很出色；各機型詳情見 [docs/raw-parity.md](docs/raw-parity.md)。
-- **最大的缺口：**
-  - **相機色彩校正：** Sony、Nikon、Panasonic、Fujifilm 和 Canon CR3 的 raw 會從各自的相機 JPEG 得到受保護的估計值，內建 ILCA-99M2、ILCE-7CR、ILCE-7M4、X-H2S、X-T4、Nikon Z 6II、Z 8 和 D5300 描述檔；仍缺少實測校正，其他 raw 或被拒絕的擬合會保留中性矩陣；
-  - **壓縮的 Olympus raw 與不受支援的 CR3 變體：** 這些在有內嵌 JPEG 預覽時會改用預覽畫面。Fujifilm 無損／有損壓縮 RAF 現在能解碼感光元件資料；[驗證與現有照片庫重新載入說明](docs/raf-compression.md)；
-  - **AI 遮色片與降噪：** 主體與天空選取目前是傳統啟發式演算法；
-  - **網路照片庫：** 預覽只讀取 raw 的標頭 — 或者，對於 CR3 或預覽標籤位於其後的 TIFF raw，只讀取稀疏規劃器指定的範圍 — 以及其內嵌的 JPEG（56.5 MB → 5.9 MB，10 秒 → 1 秒，測得於測試用的網路共用資料夾），但*顯影後*的畫面仍需要透過網路傳輸感光元件資料；詳見 [docs/raw-preview-reads.md](docs/raw-preview-reads.md)；
-  - **螢幕上的 HDR 顯示、影片，以及 Lightroom Classic 的列印、書冊與地圖模組。**
-- **接下來做什麼：** 見[依影響力排序的缺口](docs/gaps.md)和[路線圖](docs/roadmap.md)。

-
-## Quick start
-
-建置整個工作區（含桌面、網頁與 CLI 應用程式）需要 Rust 1.95 或更新版本。
-
-```sh
-git clone https://github.com/storytold/lightcraft && cd lightcraft
-cargo run --release -p lightcraft                       # 開啟你的照片庫（~/Pictures/LightCraft Library；新照片庫會先帶示範照片）
-cargo run --release -p lightcraft -- ~/Pictures/trip    # 匯入你的照片（掃描資料夾，跳過重複項目）
-cargo run --release -p lightcraft -- --memory           # 用完即丟的記憶體示範工作階段（不寫入任何內容）
-cargo run --release -p lightcraft -- --control 7980     # 附帶自動化通道
-cargo xtask web --serve                                 # 在瀏覽器中執行同一個應用程式：http://127.0.0.1:8080/
-cargo run --release -p lightcraft-cli -- render photo.jpg -o out.jpg --set light.exposure=0.5
-cargo xtask ci                                          # fmt、clippy、測試、分層、wasm 檢查
-```
-
-CI 預設使用行表除錯資訊，並依啟動時可用記憶體每 1.5 GB 開一個建置工作
-（每個 CPU 最多一個；讀不到記憶體時為 4 個），所以一台 8 GB、剩餘 6 GB 可用的機器會用 4 個任務建置，
-而一台忙碌、剩餘記憶體很少的機器會用更少。測試執行緒數隨之調整，上限為 4。若不限制，每個 CPU 各跑
-一個帶完整除錯資訊的連結器，測試還沒開始記憶體就會耗盡。GPU 測試的涵蓋範圍不受影響。明確設定
-`CARGO_PROFILE_DEV_DEBUG`、`CARGO_BUILD_JOBS` 與 `RUST_TEST_THREADS` 會覆寫這些預設值。
-日常開發指令保留各自的設定。
-
-**記憶體受限機器上的 release 建置：** [#1196](https://github.com/storytold/lightcraft/issues/1196)
-回報在一台 16 GB 的 Arch/AUR 機器上，同時建置桌面應用程式與 CLI，並啟用完整除錯資訊、thin LTO
-及單一程式碼產生單元時，連結過程遭到 OOM 終止。上述 CI 預設值並不適用於一般的
-`cargo build --release`。建議先用一個建置工作；若記憶體充足，可嘗試兩個：
-
-```sh
-CARGO_BUILD_JOBS=1 cargo build --release -p lightcraft -p lightcraft-cli
-# 或者：CARGO_BUILD_JOBS=2 cargo build --release -p lightcraft -p lightcraft-cli
-```
-
-如果打包環境啟用了完整除錯資訊或較耗記憶體的 LTO 設定，可以使用僅對本條指令生效的
-覆寫設定，降低原始碼建置所需的記憶體：
-
-```sh
-CARGO_BUILD_JOBS=1 CARGO_PROFILE_RELEASE_DEBUG=0 CARGO_PROFILE_RELEASE_LTO=false CARGO_PROFILE_RELEASE_CODEGEN_UNITS=16 cargo build --release -p lightcraft -p lightcraft-cli
-```
-
-這些 POSIX shell 賦值只影響這一條指令，不會變更全域 Cargo 設定或儲存庫的 release profile。
-停用 LTO 可能改變效能與二進位檔大小；停用除錯資訊會減少可用的除錯細節。這是建置建議，
-並不保證任何機器都有足夠的記憶體。下游打包者應逐一建置大型二進位檔、不要同時進行，並避免在低記憶體
-的建置機器上同時使用完整除錯資訊、LTO 與單一程式碼產生單元。自行匯出 profile 設定的
-PKGBUILD 可能會覆寫繼承的環境變數；請在本機調整打包腳本或聯絡維護者，而不要假設替
-`makepkg` 加上環境變數前綴就能優先生效。
-
-測試在缺少 GPU、語料庫、craft-fonts 字型或模型時會直接通過而不檢查任何內容（libtest 沒有「已跳過」
-這個狀態），所以 `cargo xtask ci` 會把它們列出來：測試會用 `lightcraft_testkit::skip!` 記錄跳過原因，
-執行結束時會列出機器提供的環境（作業系統、CPU、記憶體、每個後端的 GPU 配接器、語料庫、字型）以及每一項
-跳過的原因。它會寫入 `target/ci/report.json` 和 `target/ci/summary.md`，後者是可直接貼進 PR 的
-Markdown 區塊（`--summary-md` 會把它印出來）；`--hardware` 還會在每個有實體配接器的後端上執行
-GPU 測試。不會上傳任何內容。
-
-**中文與日文文字**需要共用字型儲存庫，這是一個可選的建置輸入（所有正式發布版都會包含它）：
-
-```sh
-git clone https://github.com/storytold/craft-fonts ../craft-fonts
-CRAFT_FONTS_DIR=../craft-fonts cargo run --release -p lightcraft
-```
-
-不指定它時，LightCraft 一樣能建置與執行，只是中文和日文文字沒有字形。字型從不提交到
-本儲存庫，字型的收錄規範記載在該儲存庫：見 [craft-fonts README](https://github.com/storytold/craft-fonts#readme)。
-
-**介面語言：** **編輯 → 語言**（English、简体中文、繁體中文（台灣）、日本語、Português (Brasil)、Español、Deutsch、Русский、Français、Українська、Čeština、ქართული）或 **設定 → 一般 →
-語言**；選擇後立即生效並會保留。詳見 [docs/localization.md](docs/localization.md)。
-
-**記錄檔：** 桌面應用程式會把記錄檔寫到標準錯誤輸出，以及設定資料夾裡的 `logs/lightcraft.log`
-（Linux `$XDG_CONFIG_HOME/lightcraft/logs/`，預設為 `~/.config/lightcraft/logs/`；macOS
-`~/Library/Application Support/LightCraft/logs/`；Windows `%APPDATA%\LightCraft\logs\`），絕不會寫進照片庫裡。
-**可攜模式：** 在執行檔旁放一個名為 `portable.txt`（或 `LightCraft.portable`）的檔案，會把設定
-資料夾移到執行檔旁的 `LightCraftData`。從桌面選單或 Dock 啟動沒有終端機，所以請把這個檔案附在
-錯誤回報裡（**說明 ▸ 開啟記錄資料夾** 會在檔案管理員中顯示它）。每次啟動會把
-上一個記錄檔移到 `lightcraft.1.log`，再上一個移到 `lightcraft.2.log`，這樣當機那次的記錄檔就能在下次啟動後
-保留下來；檔案到 16 MiB 就會停止增長，`--version` 和 `--help` 不會寫記錄檔，帶
-`LIGHTCRAFT_NO_PREFS` 執行時只會寫到標準錯誤輸出。預設情況下，LightCraft 自己的 crate 會記錄到 `info`
-層級，其他一切則記錄到 `warn`。`LIGHTCRAFT_LOG=info` 或 `debug` 的行為和以前一樣（LightCraft 自己的 crate
-用該層級，其餘只記警告與錯誤；其他值：只記警告與錯誤），並且優先於 `RUST_LOG`；未設定 `LIGHTCRAFT_LOG` 時，`RUST_LOG` 會把預設值換成
-env_logger 風格的指令，例如 `RUST_LOG=debug` 或 `RUST_LOG=warn,lightcraft_pipeline=trace`（以
-`*` 結尾的指令會涵蓋所有以它開頭的目標，如 `lightcraft*=debug`）。panic 一樣會記錄在那裡，
-並且仍然會寫在暫存資料夾裡的 `lightcraft-panics.log`。記錄器程式碼位於 `apps/lightcraft/src/logging.rs`。
-
-網頁版需要 `wasm32-unknown-unknown` target 以及對應版本的 `wasm-bindgen` CLI
-（`cargo xtask web` 會印出確切的安裝指令）；詳見 [docs/web.md](docs/web.md)。
-
-**Nix** 會建置桌面應用程式與 `lightcraft-cli`（Nix 建置永遠包含 craft-fonts 輸入，所以日文
-文字有字形）：
-
-```sh
-nix run github:storytold/lightcraft                    # 桌面應用程式
-nix build github:storytold/lightcraft                  # → ./result/bin/{lightcraft,lightcraft-cli}
-nix develop github:storytold/lightcraft                # rust 工具鏈 + 原生相依套件 + 字型
-```
-
-在 NixOS 上，請從 `nix develop` 執行 `cargo` 建置：在它之外，應用程式找不到 `libvulkan.so.1`，
-偵測不到 GPU，會改用 CPU 算繪（啟動時會印出一次提示，說明這樣會慢很多）。`nix run` 和 `nix build`
-會自行設定好路徑。
-
-在 flake 設定中（NixOS、home-manager、nix-darwin）：
-
-```nix
-# flake.nix
-inputs.lightcraft.url = "github:storytold/lightcraft";
-# 選用：使用你自己的 nixpkgs，而不是 LightCraft 鎖定的那個
-# inputs.lightcraft.inputs.nixpkgs.follows = "nixpkgs";
-
-# 然後在 NixOS 或 home-manager 模組中（`inputs` 在作用範圍內）：
-nixpkgs.overlays = [ inputs.lightcraft.overlays.default ];   # 讓 `pkgs.lightcraft` 可用
-environment.systemPackages = [ pkgs.lightcraft ];           # home-manager：home.packages = [ pkgs.lightcraft ];
-```
-
-`nix build` 會安裝與 .deb/.rpm 相同的 desktop 檔案、hicolor 圖示和 AppStream 中繼資料，並執行
-`cargo test --workspace` 作為其檢查階段（用 `pkgs.lightcraft.overrideAttrs { doCheck = false; }` 跳過）。

-
-## How it's built
-
-一個引擎優先的 Cargo 工作區，由一群小而經過測試的 crate 組成，並強制分層（`cargo xtask layers`）：`geom`、
-`color`、`raster`、`tiff` → `raw`、`codecs`、`meta`、`develop` → `pipeline` → `catalog` → `engine` → `ui-egui`。
-egui 前端是一個可替換的 crate；它之下沒有任何東西知道 UI 的存在。`mcp` 和各個應用程式（`lightcraft`、
-`lightcraft-cli`）則坐落在 `engine` 之上。
-
-## Contributing
-
-人類與代理遵循同一套規則，所以請先讀 [AGENTS.md](AGENTS.md)。重點如下：
-
-- **淨室。** 絕不閱讀 Adobe 的二進位檔或 GPL 的 raw／照片程式碼（darktable、RawTherapee、LibRaw、rawspeed、dcraw……）；
-  只依據公開規格與黑盒觀察來工作。
-- **絕不使用 Adobe 資產：** 不使用 Adobe 產品的圖示、截圖、預設集、描述檔、LUT 或字型。儲存庫中的每一張
-  影像、圖示和字型都是原創、公眾領域、創用 CC、OFL 或寬鬆授權的，並在同一次提交中
-  於 [assets/ATTRIBUTION.md](assets/ATTRIBUTION.md) 新增條目。新的字型要提交到
-  [storytold/craft-fonts](https://github.com/storytold/craft-fonts)，而不是這裡。
-- **純 Rust**、強制的 crate 分層、一切皆指令，並且每次提交前 `cargo xtask ci` 都必須通過
-  （一次提交對應一個任務 ID）。
-- **絕不當機。** 非測試程式碼要回傳錯誤而不是 panic：不使用 `unwrap()`、`expect()`、`panic!` 或
-  `unsafe`，對任何來自輸入的資料都做受檢的索引存取，並且每一個當機修復都要附一個回歸測試。細節見

-# Security Policy
-
-LightCraft reads camera raw files, image formats, metadata and sidecars, imports other photo catalogs, downloads and runs machine-learning models, and exposes CLI, JSON control, and MCP automation. Treat files, paths, metadata, catalogs, model files, automation requests, and command parameters as potentially malicious.
-
-## Reporting a vulnerability
-
-Please give the repository maintainers a reasonable opportunity to investigate and coordinate a fix before publishing exploitable details, proof-of-concept code, or weaponized files.
-
-This repository does not currently document a dedicated private security email or private reporting channel. Contact the repository maintainers through the repository owner/maintainer channels already listed in the project, provide only a minimal non-exploitable summary in public, and ask for an appropriate private transfer method before sharing sensitive details. Do not open a public issue containing a working exploit, secret, sensitive crash dump, or malicious attachment.
-
-If no private channel can be established, withhold weaponized material and report the smallest safe description that allows maintainers to make contact.
-
-## What to include
-
-A useful report includes:
-
-- affected LightCraft version, commit, or release artifact;
-- operating system, architecture, build profile (desktop or web), and relevant feature flags;
-- the affected component or path;
-- security impact and required attacker access;
-- exact reproduction steps;
-- expected behavior and actual behavior;
-- crash logs, backtraces, sanitizer output, or resource measurements when applicable;
-- whether the problem reproduces from a clean checkout;
-- any known workaround or containment.
-
-Remove credentials, personal paths, private photos, and unrelated system information from logs.
-
-## Malicious test files
-
-Do not attach a potentially harmful or non-redistributable file to a public issue. Initially provide its format, size, cryptographic hash, observed effect, provenance category (for example, synthetic or fuzz-generated), and the command needed to reproduce the problem. Coordinate a private transfer method with maintainers before sending the sample.
-
-Test files accepted into the repository must be minimized, free of personal or proprietary data, legally redistributable, and documented with the expected failure behavior. A fixed parser defect should receive a permanent regression test whenever safe and practical.
-
-## Scope
-
-Security reports may cover:
-
-- camera raw, DNG, TIFF, HEIF, JPEG and other image decoding, and EXIF/XMP metadata and sidecar parsing;
-- decompression bombs, oversized dimensions, integer overflow, memory exhaustion, recursion, or hangs;
-- the LightCraft catalog, and importing other catalogs and libraries (such as Lightroom catalogs);
-- import/export and filesystem path handling, including traversal, symlinks, and unsafe overwrite or move behavior;
-- downloading, verifying, unpacking and running machine-learning models (denoise, faces, masks);
-- engine command validation and serialization/deserialization;
-- the desktop control channel, the MCP server, and the MCP-to-app connection;
-- the WebAssembly build;
-- GPU resource validation or driver-facing input handling;
-- dependencies, CI, packaging, signing, checksums, and release artifact integrity.
-
-General bugs without a security impact should use the project's normal issue and contribution process.
-
-## Current limitations
-
-The control channel (`lightcraft --control PORT`) listens on loopback only and has no authentication, so any local process can drive the app while it is enabled; only enable it when you need it ([control-protocol.md](docs/control-protocol.md)).

-//! of the chosen printer / paper profile.
-//!
-//! - **Target**: a printer / paper ICC profile (RGB, CMYK or grey; matrix or LUT based) converts the

-//!   well-known RGB space (sRGB, Adobe RGB) and that space's profile travels with it.
-//! - **Rendering intent**: perceptual or relative colorimetric, as for soft proofing ([`ProofIntent`]).
-//! - **Black point compensation** (relative colorimetric only): the darkest colour the device holds is
-//!   measured by a round trip of black through the profile, and the page's linear values are scaled
-//!   so its black lands there instead of every shadow below it clipping to the same ink. Linear
-//!   Rec.2020 is linear in XYZ, so with source black 0 and white 1 this is the published BPC mapping
-//!   `Y' = Y·(1 − Yb) + Yb` for a neutral destination black. Perceptual tables carry their own black
-//!   mapping and are left alone.
-//! - **Print adjustment**: brightness and contrast (−100..100) for prints that come out darker or

-//! of Nikon `MEASURED_BODIES` (`crates/raw/src/vendor/nef.rs`) for bodies that record

-//!
-//! **Frame.** For each raw it aligns the largest embedded JPEG with the sensor data: both are reduced to half-size
-//! luminance (the raw by summing each 2×2 colour-filter block), and every offset that keeps the JPEG inside the data is
-//! scored by the correlation of their gradient magnitudes. The best offset is refined to sub-pixel precision; a peak
-//! that is weak, ambiguous or between two pixels is flagged. Files are grouped by model and data size (bit depths
-//! pooled: both read out the same area); when 3 clean files agree, the group prints its table entries (siblings of the

-//! must be the camera's full-size one, unrotated and without in-camera geometry corrections (distortion control off);
-//! a smaller preview is not aligned.
-//!
-//! **Edge bands.** From each edge inwards (at most 128 lines) it counts lines that hold no picture: *empty or dark*
-//! (mean below 1% of the range over black) or *masked* (flat, patternless and above black: even and odd samples
-//! alike within 4 standard errors or within 0.4% of white, since some filler holds a small fixed offset between the
