Replace the frontpage liquid-fill disk circle with a real donut split into
Apps · Docker · Other · Free, keeping disk % used in the centre. Apps come
from the per-app generator (root-device bytes), Docker from system df; both
are clamped within "used" so skew can't overflow. Live disk ticks redraw it,
and the card now clicks through to the full Storage breakdown.
