Custom providers previously never enabled prompt-cache control, so agent turns re-billed the full context every request even on cache-capable backends.
- Add `CustomProvider.anthropicPromptCaching` opt-in flag in @fusion/core types
- Set pi-ai `compat.cacheControlFormat="anthropic"` on opted-in models in both registration paths: custom-provider-registry `toProviderConfig` and pi.ts `createFnAgent`
- Expose the new toggle in the dashboard CustomProvidersSection UI (with supporting CSS) and thread it through the legacy API + custom-provider routes
- Update docs (dashboard-guide, settings-reference) to document the new setting
- Add engine test coverage for the caching flag across provider registration and pi-create-fn-agent paths
- Add changeset for the fix

Spinners, status-dot pulses, and entrance animations across the dashboard
rendered frozen: transition tokens (--transition-slow: 0.3s ease) bundle a
duration AND an easing, and 15 animation declarations reused them as bare
durations. Substituting "0.3s ease" next to an explicit easing (linear,
ease-in-out, ease-out) — or inside calc() — makes the declaration invalid at
computed-value time, which per spec resolves the entire property to
animation: none with no console error.
- add duration-only tokens (--duration-instant/fast/normal/slow) and derive
the --transition-* tokens from them so the two cannot drift
- switch all 15 broken animation declarations across 14 CSS files to the
duration tokens, preserving effective durations
- add animation-duration-tokens.css.test.ts: sweeps every app CSS file and
fails on transition-token-as-duration, calc() over a transition token, and
transition token in animation-duration
Verified in a real browser against the production build: previously frozen
.status-dot--connecting and calc-based NodesView spinners now report running
animations; transition shorthands still resolve to "0.15s / ease".

- Broaden mobile media query to include (max-height: 480px) so landscape
phones (which exceed 768 CSS px wide) still render the bottom nav and
mobile board layout instead of desktop horizontally-scrollable columns.
- Guard useMobileKeyboard against pinch-zoom (vv.scale > 1) — Android
Chrome ignores user-scalable=no, and a focused textarea + zoom was
false-positiving keyboard-open and hiding MobileNavBar.
- Read documentElement.clientHeight instead of stale window.innerHeight
when computing keyboard overlap (Android multi-window can leave
innerHeight cached at a wildly different value than the actual layout
viewport — observed 2848 while html was 797).
- Add interactive-widget=resizes-content to the viewport meta so Android
Chrome shrinks the layout viewport with the soft keyboard, matching iOS.
