+# Card Columns — плагин-вид для Obsidian Bases
+
+- **Источник:** `public/cases/card-columns-obsidian/index.html`
+- **eyebrow:** Obsidian Bases · Plugin
+- **meta description:** Кейс: Card Columns, плагин-вид для Obsidian Bases. Показывает заметки как карточки, разложенные по колонкам, с фильтрацией тегов по И/ИЛИ.
+
+---
+
+**Заметка по путям к медиа:** файлы кладутся в `public/assets/card-columns-obsidian/`, в разметке страницы пути `../assets/card-columns-obsidian/файл.webp`. Форматы: WebP (изображения, постеры), WebM + MP4 (видео).
+
+## Brief (блок метаданных на странице)
+
+- **Роль:** Продуктовый дизайн и разработка
+- **Платформа:** Obsidian Bases
+- **Статус:** Рабочий плагин, open source (MIT)
+- **Команда:** Соло, пет-проект
+
+## Введение
+
+В Obsidian появились Bases, отдельный тип файла, который показывает заметки не текстом, а в разных видах: таблицей, карточками, деревом. Стандартный вид карточек мне не зашёл: он плоский, без группировки, и в нём не разобраться, когда заметок сотни. Я хотел видеть их раскладку по колонкам, как канбан, но без лишнего веса. Так появился плагин-вид Card Columns.
+
+## Контекст
+
+Bases, это не заметка и не отдельная база данных. Это запрос к vault-у: выбираешь заметки по фильтру, и фреймворк рисует их в выбранном виде. У самого Obsidian есть встроенный вид карточек, но он одноплановый: нет группировки по свойствам, нет нормальной фильтрации. Я решил сделать свой вид, который встраивается в переключатель Bases наравне со штатными.
+
+Главное ограничение было в самом фреймворке: плагин не хранит данные, а рисует то, что выдал Bases-запрос (Sort, Filter, Properties, Search из тулбара). Значит, вся логика выборки остаётся на Bases, а моя задача, только представление и навигация по нему.
+
+## Задача
+
+Спроектировать и собрать view-плагин для Obsidian Bases: заметки из запроса показываются карточками, разложенными по колонкам, а по колонкам легко ориентироваться и отбирать нужное. Вид должен жить в переключателе Bases рядом со штатными и не ломать встроенный тулбар (сортировку, фильтр, поиск).
+
+> **Callout (📌):** Главный риск, сделать вид, который конфликтует со штатным тулбаром Bases. Тогда пользователь теряет сортировку и поиск, ради которых Bases и берут. Этого нельзя было допустить.
+
+## Решение
+
+Плагин добавляет в Bases вид «Columns». Карточки строятся из результатов Bases-запроса, группировка задаётся свойством, а отбор, кликабельными тегами.
+
+### Группировка по любому свойству
+
+Колонки формируются из Group by в тулбаре Bases, по тегу, статусу, категории или любому frontmatter-свойству. Меняешь свойство в запросе, и доска пересобирается сама. Так одна и та же база закрывает разные разрезы: проекты по статусу, заметки по тегам, задачи по приоритету.
+
+### Фильтр тегов по И и ИЛИ
+
+Это то, ради чего плагин и задумывался. Под тулбаром, пилюли тегов, по клику они отсеивают карточки по всем колонкам сразу:
+
+- Левый клик по тегу, показать только его (сбрасывает остальные фильтры).
+- Левый клик по следующему тегу, показать заметки с ЛЮБЫМ из выбранных (режим ИЛИ).
+- Ctrl+Клик или правый клик, переключить тег, не сбрасывая выбор.
+- Кнопка OR/AND, переключить между «любой из» и «все перечисленные» для нескольких тегов.
+- All, снять все фильтры.
+
+Связка «ИЛИ-добавление левым кликом + точный toggle через Ctrl» получилась интуитивной: быстрый отбор не сбивает то, что уже выбрано. Альтернативу, вынести фильтр в модалку, отверг сразу: лишний клик и потеря контекста того, что уже отфильтровано.
+
+### Карточки и обложки
+
+По каждой заметке рисуются свойства как чипы, текст, теги, ссылки, булевы, даты. Можно показать обложку: из первой картинки в заметке или из отдельного свойства. У обложки полный контроль, соотношение сторон (Auto, 1:1, 3:2, 4:3, 16:9), рамка, вписывание (cover/contain), ориентация и место на карточке (над заголовком, под ним, после всего).
+
+### Что заведено в настройки
+
+Всю внешнюю вариативность я вынел в gear-меню, разбив на четыре секции, чтобы вид подстраивался под разные базы, а не под мой единственный сценарий.
+
+**General**
+
+- Куда открывать карточку: активная панель, всплывающее окно, новая вкладка, сплит вправо / вниз.
+- Ширина карточки (px).
+- Колонок в группе (1–6), сетка внутри колонки.
+- Зебра колонок (чередование фона для сканирования).
+- Masonry-раскладка (карточки заполняют вертикальные пустоты).
+
+**Title**
+
+- Перенос заголовка, жирный заголовок, размер шрифта (px).
+
+**Properties**
+
+- Раскладка чипов: стек (вертикально) или сетка (компактно в строку).
+- Перенос многострочных значений, размер шрифта.
+- Формат даты и даты-времени + локаль (Moment.js).
+
+**Cover**
+
+- Источник: нет / первая картинка в заметке / свойство-обложка.
+- Стиль (без рамки / с рамкой), соотношение сторон, ориентация, вписывание, позиция на карточке.
+
+> **Callout (💡):** Сплит-превью сделал как в самом Obsidian: левый клик переиспользует панель, Ctrl+Клик, новую вкладку внутри сплита. Без этого на широком экране карточки неудобно просматривать рядом с доской.
+
+### Работает внутри штатного тулбара
+
+Вид цепляется к BasesView-фреймворку, поэтому сортировка, фильтр, свойства и поиск из тулбара Bases остаются рабочими. Плагин только рисует результат запроса, данные не дублируются и не зависят от отдельного хранилища.
+
+## Результат
+
+Вид закрыл мою боль: Bases-запрос теперь читается как доска, а не как плоская лента карточек. Группировка по свойству + отбор по тегам И/ИЛИ, то, чего не хватало штатному виду. Всё крутится на запросе Bases, так что перенос vault-а и синхронизация ничего не ломают.
+
+Метрики у пет-проекта нет, и придумывать её не стану. Проверяю проще: юзабилити на себе в ежедневной работе. Критерий, сколько действий нужно, чтобы отобрать заметки по двум тегам и найти нужную карточку. В штатном виде карточек это был скролл ленты с ручным поиском по заголовкам; здесь, два клика по пилюлям и колонка перед глазами. Если бы замерял всерьёз, считал бы время на задачу на выборке из 20–30 заметок до и после, но на своей повседневной базе разница заметна и без секундомера.
+
+Что сделал бы иначе. Drag-and-drop карточек между колонками не стал делать сознательно, это меняет свойство в заметке, и для view-плагина это отдельный риск целостности данных. Но вижу запрос на это у пользователей, и, возможно, добавлю как опциональный режим. А пока плагин живёт вручную (через community-каталог ещё не прошёл), это единственное, что мешает им пользоваться сходу.
+
+> **Callout (✅):** Главный вывод: вид для Bases получается рабочим только тогда, когда он уважает тулбар фреймворка. Я добавил представление, а не вторую систему хранения, и заметки остались обычными заметками.
+
+## Медиа-плейсхолдеры (в HTML закомментированы)
+
+| Слот | Файл | Что показывать |
+|---|---|---|
+| Обзор | `overview.webp` | Вид Card Columns поверх `.base` файла |
+| Колонки | `board.webp` | Колонки карточек с группировкой по свойству |
+| Фильтр | `filter.webm` / `filter.mp4` + `filter-poster.webp` | Фильтрация по тегам, OR и AND |
+| Настройки | `settings.webp` | Gear-меню с секциями |
+
+Ещё один слот (`note-before.webp`) остался в шаблоне из ранней версии и сейчас не используется, удалить при вставке медиа.
+
+## Источники фактуры
+
+- Репозиторий: `https://github.com/mamadaevv/card-columns` (лицензия MIT).
+- Все параметры кастомизации и логика фильтрации взяты из README репозитория.
+- Drag-and-drop в плагине **отсутствует**: он есть у соседнего `ewerx/obsidian-bases-kanban`, не путать.
