 ## 2026-06-13 - Added screen reader text for tooltip divs
 **Learning:** When using `title` attributes on non-interactive elements like icon-only `div`s for tooltips, screen readers might not announce them properly because they aren't focusable. The visual tooltip is not enough for accessibility.
 **Action:** Always add a visually hidden `<span className="sr-only">[Tooltip Text]</span>` inside non-interactive elements that rely on a `title` attribute so that screen readers have text content to announce.
-
 ## 2026-06-18 - Added keyboard accessibility to scrollable regions
 **Learning:** Horizontally scrollable regions (like the `SectionRoadmap` component) are not accessible to keyboard-only users unless they can receive focus. Keyboard users must be able to focus the container to scroll its content using arrow keys.
 **Action:** For proper keyboard accessibility in custom scrollable regions, always include `tabIndex={0}`, an appropriate `aria-label`, `role="region"`, and explicit focus visible styling (e.g., `focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-cyan-300`).
-
 ## 2026-06-19 - Internationalization
 **Learning:** The desktop app uses i18n via json files located in `apps/desktop/src/locales/`
 **Action:** When adding new text strings, make sure to add it to all locale files.
-
-## 2026-06-25 - Native tooltips on disabled elements
-**Learning:** Standard HTML `title` attributes used as tooltips do not render on elements that use Tailwind's `pointer-events-none` class, which is often applied to `disabled:` variants in Base UI and styled components.
-**Action:** Do not rely on native `title` attributes for explaining disabled states on buttons with `pointer-events-none`. Instead, either use a custom tooltip component or ensure focus/interactive styles are preserved if an explanation is strictly required.

-## 2024-06-29 - 비활성화된 네이티브 버튼의 툴팁 차단
-**Learning:** 네이티브 `<button>` 요소에 `disabled` 속성을 사용하면 마우스 호버 이벤트를 포함한 포인터 이벤트가 완전히 차단되어 표준 HTML `title` 속성이 툴팁으로 표시되지 않으며, 키보드 탭 순서(tab order)에서도 제외됩니다.
-**Action:** "출시 예정" 등 설명 툴팁이 필요한 비활성화된 액션 버튼의 경우, `title`을 버튼에 직접 붙이는 대신 포커스 가능한 `span` (`<span tabIndex={0} title={...} role="button" aria-disabled="true">`)으로 버튼을 감싸서 시각적 및 스크린 리더 접근성을 모두 보장해야 합니다.
-
-## 2024-07-01 - Testing components with focusable disabled button wrappers
-**Learning:** When native disabled buttons are wrapped in a focusable `span` to provide accessible tooltips, tests that previously found and clicked the `button` (by temporarily removing the `disabled` attribute) may fail or become overly complex. It is cleaner and more accurate to query the wrapper element (e.g. via its `title`) and fire events on it, reflecting the actual accessible DOM structure.
-**Action:** When testing UI components that wrap disabled buttons in a focusable span for accessibility (e.g., using a tooltip/title), use `screen.getByTitle(...)` to query the wrapper element for interactions like `fireEvent.click` rather than `screen.getByRole('button')`.
