Vegas bakes each plugin's pictures into one strip, so a card already on its way across the panel keeps what it showed when it was drawn. This adds the API and bookkeeping for content that can be updated in place; the worker that redraws and swaps it follows separately. No shipped plugin implements the hook yet, so nothing changes for users. Plugin API (core 3.8.0), all no-ops by default: - BasePlugin.get_vegas_elements() -> [VegasElement(key, image, version, live, refresh_hz)]: named, fixed-width pieces of Vegas content. - BasePlugin.redraw_vegas_element(key, width, height, at): a lock-free redraw for content that changes with time. - BasePlugin.notify_vegas_data_changed(): data that lands outside update(). - src/plugin_system/vegas_elements.py (VegasElement, re-exported from base_plugin). Core: - PluginAdapter asks a plugin that implements the hook for elements on the background fetch only (under its lock, on its own canvas); every other path keeps get_vegas_content(). Live elements are pinned (padded with content_padding, never trimmed), tagged with their key, digest and data epoch in Image.info so the existing cache and group plumbing carry them unchanged, and untagged if a width budget crops them. - RenderPipeline records where each live element lands (ElementRecord), in absolute strip columns a trim does not move; the block-start arithmetic is shared with the STATIC markers. - PluginManager update listeners (add/remove_update_listener, notify_data_changed): told the moment update() completes, not at the next ~4s Vegas poll. The coordinator uses one to move each plugin's data epoch on. - vegas_scroll.live_refresh (kill switch), live_max_hz, live_min_interval, live_lead_screens; per-plugin core-owned vegas_live. Live elements are off under multi-display sync, in swap mode and with offscreen_prefetch off. - scripts/check_plugin.py checks the element contract (src/plugin_system/testing/vegas.py); test/fixtures/plugins/vegas-live-stub is a working example.
