Rebuild the example site as a bleeding-edge dwind/dominator showcase

[JedimEmO]

The docs site was a competent dark landing page, but it demonstrated almost nothing that DOMINATOR can do beyond static markup. This turns it into an argument for the stack.

The through-line

Every effect added here is a Mutable written by an event and read by a style_signal. No animation library, no requestAnimationFrame loop, no re-render — an event writes a number and DOMINATOR writes exactly the properties that depend on it.

// fx.rs — the whole spotlight, minus bookkeeping
.event(move |e: events::PointerMove| {
    pos.set_neq(normalised(&element, e.mouse_x() as f64, e.mouse_y() as f64));
})
.style_signal("--sx", pos.signal().map(|(x, _)| format!("{:.2}%", x * 100.0)))

What's new

Module	What it adds
fx.rs	Pointer spotlight + 3D tilt, magnetic controls, drifting aurora field, film grain, blueprint grid, scroll-spy, marquee, word-stagger kinetic headlines
palette.rs	⌘K command palette — fuzzy search over every route with word-start scoring, full keyboard control, glass panel
pages/signal_lab.rs	The new home-page centrepiece: four Mutables fan a card stack while a live code panel regenerates the Rust behind it
styles.rs	App-level keyframes, glass surfaces, grain and masks — pulled out of the old inline APP_KEYFRAMES const

The reactivity lab is the honest version of the pitch: it counts actual property writes next to a re-render count that stays at zero. Dragging a slider measured 10 → 75 property writes, 0 re-renders.

The shell gains a scroll-progress rail, route transitions with scroll reset, and an active-route indicator that grows in. Docs gain a sticky glass sidebar with a search affordance, breadcrumb mastheads, gradient section rules, and prev/next pagers. The utility showcase gains a scroll-spy chapter rail.

The palette is reachable from the header chip, the docs sidebar search box, ⌘K/Ctrl+K, or /.

Two real bugs fixed on the way

• The hero used @lg:, which is 1920px in dwind, so it stacked into a single column on every normal desktop. It wants @md: (1280px).
• The palette's entrance animation used fill-mode both, which silently overrode the inline transform that centred it — the panel sat right-of-centre. Centring moved to a wrapper node so the keyframes own transform alone.

Verification

Driven in real Chrome via playwright-core:

• All 19 routes render with zero console errors
• No horizontal overflow at 1440px or 390px
• prefers-reduced-motion honoured — marquee, sheen, tilt and reveal all stop, and kinetic words sit at opacity 1
• Palette verified end to end: opens on Ctrl+K, trans ranks Transforms above dwind on crates.io, arrows/enter navigate, escape dismisses
• Spotlight tracking verified live (--sx: 24.83%, data-hot: 1, rotateX(1.61deg) rotateY(-2.01deg))
• cargo fmt clean, no new clippy warnings
