Cmd+V paste not working in Cmd+F search bar

Normalized all text input handlers (tab rename, tab note, URL input) to use inpututil.IsKeyJustPressed for paste — consistent with pane rename

Light theme: all 16 ANSI colors now meet WCAG AA (7:1+ contrast against #FAFAF8) — previous palette had 11 colors below 4.5:1, worst offender bright_white at 1.2:1

Block rendering Y offset: include pane header height in geometry calculations

Blocks only render after command completes (no janky growing border during execution)

Clear stale block positions on window resize; keep active block so first post-resize command works

show_border config option for blocks: when false, hides border/bg tint but keeps badges and hover copy buttons

Clipboard encoding in .app bundles: set LANG=en_US.UTF-8 at startup so pbcopy/pbpaste handle multi-byte UTF-8 correctly (em dash, CJK, etc. no longer paste as mojibake)

Resize lock starvation during heavy PTY output (concurrent RLock/Lock ordering in pty.go)

DECOM origin mode scroll region, DECRC/RCP cursor clamp, ECH wide char overlap

Primary scroll region preserved across alt screen toggle (no longer lost after TUI exit)

Alt screen wrapped slice deep-copied instead of aliased

Gray background on window resize (missing screenDirty flag)

Mouse click and drag snap to parent cell when landing on wide char continuation

Word selection expands correctly across wide characters

Search highlights span the correct columns for wide characters (colMap pattern)

URL detection handles wide characters in surrounding text

Resize fixes truncated wide chars at boundaries and orphaned continuation cells

FFMPEG recorder missing last frames on stop — replaced mutex-guarded writes with buffered channel + dedicated writer goroutine that flushes before closing stdin

FFMPEG recording playback speed too fast — duplicate frames inserted to fill timing gaps when capture intervals exceed 33ms, keeping playback aligned with wall-clock time

Explicit output frame rate (-r 30) added to ffmpeg command

Markdown parser replaced with goldmark (GFM extension) for robust AST-based rendering

Table columns are now aligned with computed max-width padding
