Subject: [PATCH] feat(ui): shared /style.css + top nav across landing and
 /apps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Slice 1 of the on-box UI uplevel. Consolidates the two duplicated
stylesheets (landing's webinstaller/app.py and /apps's inline block
in furtka/api.py) into one sheet served by Caddy at /style.css.
Expands the token set (spacing, radii, shadows, focus ring, warn-fg,
accent-soft, card-hover), adds a prefers-color-scheme light theme,
and introduces shared primitives for later slices: .nav, .chip,
.card, .kv, .coming, .grid-apps, .app-tile, .app-icon.

Also adds a persistent top nav (Home / Apps) to both pages — Jakob's
Law, so users always have a way back — and collapses the /apps "Last
action" log behind a details disclosure so it stops dominating the
page. Format fallout on drives.py picked up by ruff.
