   Reuses the start-screen hero + menu language; adds a one-line hint under
   each tool tile and an ON/OFF treatment for the two toggle tiles.
   `.ob-start .gh-stage` (not bare `.gh-stage`): the hub's overlay carries both
   `.ob-start` and `.gh-hub` (it reuses the start-screen chrome), so its stage
   also matches `.ob-start .ob-stage` above. A bare single-class `.gh-stage`
   selector loses that specificity tie (2 classes beats 1) and the hub used to
   render at its own narrower column instead of the shared shape. Matching
   the ancestor + own-class shape here makes this rule win.
   Widened to the start screen's own shape (was a 560px single column pre-
   two-column pass) — the hub now hosts two side-by-side `.gh-menu` columns
   under the shared hero, same width budget as `.ob-start .ob-stage`. */
