v0.1.5

Fixes

• EPUB links inside a chapter now actually navigate. Clicking a table-of-contents entry, a footnote, or a cross-chapter link in the book's own content used to no-op — only TOC-sidebar clicks worked. All in-book links now jump to the right page; external http(s) links open in your system browser instead.
• HUD toolbar and Settings button no longer swallow clicks in their own empty margin. Clicking near an icon, but not quite on it, could silently miss and land on the page underneath instead.
• EPUB highlights now land on the correct line, and the eraser works again. A CSS rule meant to cap embedded book images/illustrations was also shrinking the invisible layer highlights are drawn on, so highlights could render off the selected line — worse near the bottom of a page — and eraser clicks aimed at a highlight could miss it entirely.
• The highlighter color swatch no longer stays "selected" while the eraser is active. It now only shows as active while the highlighter tool itself is in use.

Toolbar changes

• The highlighter's color/eraser flyout no longer expands by default — hover the highlighter button to reveal it.
• The HUD toolbar moved to the right edge (it was overlapping the table-of-contents panel on the left) and now horizontally aligns with the Settings button.
• Hovering either the HUD toolbar or the Settings button now reveals both — no need to re-aim your cursor between them.
• The HUD toolbar hides automatically while the Settings panel is open, instead of overlapping it.
