     Clusters words vary a lot in length (EYE .. BACKGAMMON).
     1) min-width: 0 stops a grid track sizing itself to its widest word's
        min-content, which otherwise breaks the 1fr columns' equal widths
        and (via aspect-ratio) makes some rows visibly taller than others.
     2) justify-items: stretch overrides pp-tile's place-items: center on
        the inline axis only, so the implicit single-column grid inside
        the button resolves to the button's full definite width instead of
        shrinking to the word's own max-content width. Without it, a
        percentage width on .cl-tile__word resolves against an "auto"
        (content-based) track and computes as auto too, so long words
        never wrap, they just overflow past the tile's border. */
