💡 What: Added keyboard accessibility to the ecosystem dropdown menu using purely CSS techniques, without requiring JavaScript. Added a journal entry to document the pattern.
🎯 Why: Keyboard users cannot open dropdown menus triggered purely by :hover. This prevents them from accessing the internal ecosystem navigation links.
Accessibility: Users navigating with the "Tab" key can now open the dropdown menu natively since the menu visibility includes :focus-visible on the button and :focus-within on the dropdown itself. Also linked elements with aria-controls for screen reader semantic pairing.

- Added `aria-controls` to the trigger button and `id` to the dropdown menu to link them for screen readers.
- Added `aria-hidden="true"` to the decorative dropdown arrow.
- Modified `assets/css/custom.css` to add `focus-visible` and `focus-within` visibility rules so that the dropdown natively works for keyboard users.
- Added UX journal entry for the CSS-only keyboard accessibility pattern.
