+### 6. BookInfoActivity UI Integration (`src/activities/home/BookInfoActivity.cpp`)
+- Added `GUI.drawHeader()` call to show the standard header bar (clock, battery, "Book Info" title)
+- Replaced hardcoded `MARGIN = 20` with theme metrics (`contentSidePadding`, `topPadding`, `headerHeight`, etc.)
+- Content now starts below the header bar using `metrics.topPadding + metrics.headerHeight + metrics.verticalSpacing`
+- Y-culling stops content above button hints using `pageH - metrics.buttonHintsHeight - metrics.verticalSpacing`
+- `contentHeight` includes bottom padding for button hints so scrolling accounts for the reserved hint area
+
 ## Commits
 - `8025e6f` — `feat: parse and display all available EPUB metadata fields`
-- (pending) — `refactor: consolidate Epub blank strings, simplify BookInfo buildLayout`
+- `efa727e` — `refactor: consolidate Epub blank strings, simplify BookInfo buildLayout`
+- (pending) — `fix: add header bar and fix bottom spacing in BookInfo`
 
 ## Follow-up
 - Existing book caches will auto-invalidate (version 6 → 7) and regenerate on next load
