## Summary - Add CSS `display: none` support to the EPUB rendering pipeline (fixes #1431) - Parse `display` property in stylesheets and inline styles, with full cascade resolution (element, class, element.class, inline) - Skip hidden elements and all their descendants in `ChapterHtmlSlimParser` - Separate display:none check for `<img>` tags (image code path is independent of the general element handler) - Flush pending text blocks before placing images to fix layout ordering (text preceding an image now correctly renders above it) - Bump CSS cache version to 4 to invalidate stale caches - Add test EPUB (`test_display_none.epub`) covering class selectors, element selectors, combined selectors, inline styles, nested hidden content, hidden images, style priority/override, and realistic use cases
This directory is intended for PlatformIO Test Runner and project tests. Unit Testing is a software testing method by which individual units of source code, sets of one or more MCU program modules together with associated control data, usage procedures, and operating procedures, are tested to determine whether they are fit for use. Unit testing finds problems early in the development cycle. More information about PlatformIO Unit Testing: - https://docs.platformio.org/en/latest/advanced/unit-testing/index.html
