Module renamed github.com/harrybrwn/patterm → github.com/hjbdev/patterm across imports. Chrome: - Palette redrawn with rounded box-drawing borders, accent left-bar for the selected item, dim hints, and a separator-aware footer. - Tab bar grew from 1 row to 3: labels with breathing room, a dim argv subtitle truncated to each tab's width, and an accent thick underline for the focused tab with a faint divider extending across the rest of the host width. Layout, viewport-renderer, and screen- renderer tests updated for the new mainTop. - Sidebar reuses the same palette: accent section headers, `▎` selection marker, `●`/`○` status glyphs, dim previews. - Shared SGR constants moved into internal/app/style.go. Palette input: - Adjacent duplicate arrow events (legacy `\x1b[B` + kitty `\x1b[57353u` for one keypress, or two of the same form) are now collapsed via peekArrowEvent + chunk-level dedupe in processStdin. - On open, push `\x1b[>0u` onto the host's kitty keyboard stack so palette input is in plain legacy mode regardless of what the child pushed (codex/ratatui pushes its own flags which had been leaking to the host). Popped on close. Tab-switch repaint (repaintFocused): - Use the emulator's SerializeVT bytes (with SGR / cursor / DECSTBM / tabstops) instead of plain text, fed through the per-focused viewport renderer so the shifter translates row positions. - Prelude resets host SGR / DECOM / DECSTBM (pinned to viewport) / cursor visibility before the replay, so leftover modes from the previously-focused child don't distort the new snapshot. - Re-emit the saved cursor as a child-space CUP after the serialized bytes so the host cursor lands at the emulator's actual position (overriding DECSTBM's home side-effect and the tabstop-setup CHA sequences) AND the renderer's vr.row/vr.col get re-synced via trackCSI. - cursorShifter now carries childRows and rewrites empty `\x1b[r` to `\x1b[<mainTop>;<mainBottom>r` (host coords) — the default (1,1) shifted to (4,4) was producing a one-row scrolling region that scroll-exploded the replay. - After the snapshot lands, nudge the focused child with a one-row PTY winsize toggle so the kernel emits SIGWINCH and ratatui-style TUIs throw away their diff state and emit a fresh frame. Codex still renders incorrectly after a focus switch; see TODO.md "Switch-back render divergence" for the deep investigation handoff.
