The fixed 140px width on the timeline TD reserved a lot of empty space to the right of the date — on narrow viewports it squeezed the cards severely. Replaced the hard width with the standard \`width:1%\` email-table trick so the cell collapses to whatever the date line actually needs (about 80-95px); the card column inherits the rest. Right padding dropped from 14 to 4 to tighten further.
