## 2024-05-15 - Enhancing Generated File Tree HTML
**Learning:** Raw directory listings generated into HTML often lack critical accessibility meta tags (like `lang="en"`, `viewport` for responsive scaling) and aria-labels for directory/file links (which are otherwise non-descriptive for screen readers like just `📁 folderName`).
**Action:** Always include base semantic structures (`<main>`, `<html lang="en">`, responsive meta tags) and `aria-label`s specifying the entity type (e.g., `folderName directory`) when generating raw navigation trees to ensure keyboard and screen-reader usability. Add `:focus` styles mimicking `:hover` for keyboard users.

## 2024-05-18 - Improve Screen Reader Experience for Directory Trees
**Learning:** Decorative unicode icons (like &#128193; for folders or &#x21B0; for back arrows) in generated HTML directory listings are read aloud by screen readers as confusing literals, degrading the user experience.
**Action:** Wrap decorative emoji and unicode symbols in `<span aria-hidden="true">` to prevent screen readers from announcing them, and add explicit `aria-label` attributes to ambiguous links (like `..`) to provide context.

## 2024-06-25 - Directory Listing Navigation Landmark
**Learning:** Generated directory listings act as navigation regions, and screen readers benefit when the listing is announced separately from the page's main content.
