// IMPORTANT PERFORMANCE OPTIMIZATION BELOW

// * :nth-of-type(1n+70) - makes sure we do not render lines 71+ right
// away. Even though the HTML is injected in the DOM, as long as we do
// not render those lines, the browser doesn't need to spend resources
// calculating and repainting what's hidden.
//
// * :not(:last-of-type) makes sure that we output the last line of the
// blob's snippet. This is important because the column with the line
// numbers has auto width and is expanding based on the content in it.
// This leads to unnecessary layout shift when the last lines of the
// snippet are longer than two (2) digits.
// EXAMPLE: Let's say, we have a blob with 100 lines. If we output 70
// lines, and then, the remaining 30 (incl the line 100), it will lead
// to the layout reflow and styles recalculation when we output line
// 100 (because the width of '100' is always bigger than '70'). By
// outputting the last line right away, we prevent that as the column
// will always be expanded to the maximum needed width.
