+## [0.1.4] - 2026-07-01
+
+### Fixed

+- Mobile: the resume header's "binary.semaphore / resume" lockup overlapped the
+  theme toggle and sign-in on phones. Phones now show just the "b." mark (keeping
+  the "/ resume" links), with layout guards so the header groups can't overlap;
+  the full lockup returns at the `sm` breakpoint.
+- Mobile: the editor toolbar packed home / title / template / tune / json /
+  export into one non-wrapping row, which overflowed and squeezed the title field
+  to nothing. It now wraps (title row full-width, actions flowing below) on small
+  screens and stays a single row on wider ones.
+- The "tune" popover is capped to the viewport width so it can't hang off-screen
+  on narrow devices.
