/*
 * « Tuiles de renvoi » — link tiles towards the sub-pages of a section. Loaded
 * only when a group carries .is-style-gb-renvoi; the mosaic itself (native grid,
 * joined tiles, breakpoints) comes with .is-style-gb-mosaique (grille.css).
 *
 * The tile is drawn like a mosaic tile (grille.css, .is-style-gb-tuile), with a
 * heading that is the link. The whole tile answers to the pointer over it and to
 * the keyboard focus inside it (:focus-within), but only the link is focusable:
 * one tile, one destination, one tab stop.
 * Hover changes ink only — never the geometry of the container.
