Renderer, xterm, and plugin cards follow the same wheel focus matrix as normal scale: only a focused input-bearing card can keep wheel in Off or released-Key mode; On, an active Key binding, or the held full navigation override gives it to the canvas. A Browser summary or other non-native placeholder is always canvas-owned for wheel/pinch. - Every terminal edge and corner is a resize target. The minimum card size is `420 × 260`; resizing updates the xterm viewport and preserves the opposite edge. - Live terminal selection follows the visible pointer position at every canvas zoom. Copy and paste use the selected preset's editable terminal bindings: Linux defaults to `Ctrl+C`/`Ctrl+Shift+V`, Windows to `Ctrl+Shift+C`/`Ctrl+Shift+V`, and macOS to `Cmd+C`/`Cmd+V`. Plain `Ctrl+C` without a selection retains the PTY interrupt. Presets use Enter to submit and Shift+Enter for a newline in the optional Codex editor; other CLIs retain their editor policies. +- Controls includes an off-by-default **Copy on selection** setting, persisted and applied immediately to every agent and terminal, including fullscreen cards. Completing a non-empty mouse selection copies its text to the system clipboard without clearing the highlight; search results and cleared selections do not copy. With the setting enabled, Shift forces text selection in mouse-reporting TUIs on all desktop platforms; on macOS the terminal mouse adapter translates it to xterm's Option selection without taking the canvas's Option navigation binding. - Canvas plugin apps use the same movable card grammar, `54px` header, resize/snap behavior, and semantic summary below `0.5×`. A `window` contribution opens a separate CanvasTTY-owned sandboxed window; arbitrary native window embedding is not part of the contract. - The built-in Browser is one movable, resizable core canvas card, not a plugin contribution. It uses the same `54px` outer window header as other canvas cards, with its identity and hide-card action isolated from the internal tab strip below. Its trusted DOM chrome owns compact tabs/favicons, address/search, back/forward/reload, downloads, per-tab provider badges, site dialogs, and explicit Close tab/Close all. Hiding the card keeps its tabs and shared authenticated Chromium profile alive. Below `0.5×`, during Edit HOME, behind trusted dialogs/popovers, and while overlapped by a higher renderer-owned canvas window, the native page is hidden and replaced with a stable semantic surface. During card or camera motion it remains live and follows frame-coalesced viewport geometry. - An authenticated connection or heartbeat alone never shows agent presence. A branded badge appears only after that agent actually issues a browser command, and its cursor appears only after a real pointer position exists. Claude uses `#D97757`, Codex `#10A37F`, Qwen `#6D44E8`, Kimi `#7C5CFC`, OpenCode `#5A5858`, Hermes `#D6A700`, and an unknown provider `#7A8291`.

Browser summary и другие non-native placeholder-поверхности всегда передают wheel/pinch канвасу. - Любая грань/угол terminal — resize target. Минимальный размер `420 × 260`; resize обновляет viewport xterm и сохраняет противоположную грань. - Selection живого терминала следует за видимой позицией указателя при любом canvas zoom. При непустом выделении `Ctrl+C`/`Ctrl+Shift+C` или `Cmd+C` копирует; `Ctrl+Shift+V`/`Cmd+V` и `Shift+Insert` вставляют из system clipboard. Обычный `Ctrl+C` без выделения остаётся PTY interrupt. `Shift+Enter` отправляет line-break sequence (`ESC [ 13 ; 2 u`) в PTY вместо отправки строки. +- В «Управлении» есть выключенная по умолчанию настройка **Копировать при выделении**. Она сохраняется и сразу применяется ко всем агентам и терминалам, включая полноэкранные карточки. После завершения непустого выделения мышью текст копируется в системный буфер, подсветка сохраняется. Поиск и снятие выделения не запускают копирование. При включённой настройке Shift позволяет выделять текст в TUI, перехватывающих мышь, на всех desktop-платформах; на macOS адаптер мыши терминала переводит Shift в Option для xterm, сохраняя навигацию канвасом через Option. - Canvas plugin apps используют ту же movable card grammar, header `54px`, resize/snap и semantic summary ниже `0.5×`. Contribution `window` открывает отдельное sandboxed окно под управлением CanvasTTY; произвольные native windows не встраиваются. - Built-in Browser — одна movable/resizable core canvas card, а не plugin contribution.

Trusted DOM chrome владеет tabs/favicons, address/search, back/forward/reload, downloads, per-tab provider badges, site dialogs и явными Close tab/Close all.

Ниже `0.5×`, в Edit HOME и за trusted dialogs/popovers native page скрывается и заменяется стабильной semantic surface.
