Same companies grid, same data, rendered four ways in a fixed 1400px viewport (overflow clipped, as in the app). Plain DOM <table>, 13px cells, 12px / 550 headers, 8px cell padding, 1px right/bottom borders #ececf1, nowrap + ellipsis, tabular numerals. Columns auto-fit their widest content (capped for text columns), so a narrower face directly changes how many columns fit. Column count excludes the checkbox and row-number gutters.
