/* ---------- Work index page: stacked-column masonry ----------
   CSS multi-column (column-fill:balance) needs the container's height known
   up front to decide where to break — with 80-odd tiles that collapsed the
   whole grid to 0 height, and column-fill:auto just dumped every tile into
   the first column. A plain CSS grid sidesteps that but locks tiles to
   shared row boundaries, so a short tile leaves dead space below it before
   the next row starts. Splitting the tiles into N independent flex columns
   (built in JS, see main.js) avoids both problems: each column just stacks
   its own tiles with a normal gap, no height-balancing step involved. */
