StandTerm v2.6.6

v2.6.6 Release Notes

• Fixed horizontal and vertical seams in background terminal PNGs by rendering Unicode Block Elements as exact canvas rectangles instead of font glyphs.
• Preserved the foreground xterm DOM rendering path and normal font rendering for text, shade glyphs, box drawing, and wide characters.
• Added a reusable ANSI terminal rendering test card covering full blocks, half-block boundaries, progress bars, explicit cell backgrounds, colors, and wide text.
• Added pixel-level browser regression coverage for full-block continuity and half-block seams over non-default cell backgrounds.
