Two engine fixes in web/orchestration.sx (rebuilt into the WASM bytecode) plus the
blog CSS that surfaces them.
1. Retry on NETWORK failure, not just HTTP errors. The fetch error/catch path (the
real offline / DNS / connection-refused case) previously dispatched
sx:requestError and stopped — only a non-ok HTTP response with an empty body
ever reached handle-retry. So "no connection" never recovered. Now the catch
path calls handle-retry too, so an sx-retry element actually self-heals when the
connection returns (the cap bounds the backoff interval, not the attempt count —
it retries forever).
2. Visible failure state. On any failed/aborted fetch the engine adds an `.sx-error`
class to the element (cleared, with the retry backoff reset, on the next
success). Without it a stuck retry loop is invisible — the picker just sits
"Loading…". The blog shell ships CSS so the relate picker shows "Connection
problem — retrying…" / "offline, retrying…" on .sx-error.
Platform-wide: any sx-get/sx-post element benefits, not just the picker.
Tests: relate-picker.spec.js gains a 6th case — abort relate-options, assert
.sx-error appears, un-abort, assert it clears and the picker repopulates (proving
the retry loop is live). 6/6 browser + 272/272 conformance. WASM web stack rebuilt
(orchestration.sxbc + the static hs-* copies refreshed by the same build).
