Retrying the missed items could leave the feed on a stale position: the
retry swaps the queue (8 slides -> 3) and resets the scroll on the OLD
element, while the browser was still finishing a smooth scroll or snap.
Depending on the engine that could strand the viewport past the new
content (blank feed with the header still showing the old counter), and
the results slide kept its inner scroll because it has no key.
- The scroller now carries key={runId}, so every run mounts a brand-new
element: scroll position 0, fresh snap state, no inherited inner
scrolls in any slide.
- The scroll listener re-attaches to the new element (deps [runId]).
New retry suite 12/12: plain retry (fresh element, slide 1, header
Retry 1/N, missed item answerable again), retry fired mid smooth-scroll,
double-tap retry, and retry -> answer -> results -> retry again — all
land on slide 0 with content visible. Regression 74/74, mobile 51/51,
i18n 27/27. Lint + build clean. SW freezmo-v19.

* Freezmo service worker (production only).

*
|
|
* Strategy, deliberately conservative:
|
|
* - API routes are never cached and never intercepted.
|
|
* - Navigations: network first, falling back to the cached shell, then /offline.
|
|
* - /_next/static + icons: stale-while-revalidate (fast, self-healing).
|
|
* - Everything else: straight to the network.
|
|
*
|
|
* Bumping CACHE_VERSION is how a new deploy invalidates old assets.
