Phase-2 UI for the per-workload deploy_strategy shipped in e3d140c (which
was only reachable via the advanced-JSON editor). Adds DeployStrategyField,
a two-card radiogroup (recreate vs zero-downtime/blue-green) with CSS-only
motion glyphs that animate the deploy semantics — recreate shows the
downtime gap between versions, blue-green shows the overlapping cutover.
WAI-ARIA radiogroup with roving tabindex + arrow-key selection; respects
prefers-reduced-motion.
The field rides inside each source's *FormState via the shared sourceForms
module, so /apps/new and /apps/[id] need no changes:
- seed reads deploy_strategy; serialize is conditional-emit — the key is
written ONLY when the operator deviates from the source default, so an
untouched source_config stays byte-identical ('' is the canonical
default, resolved by the backend's effectiveStrategy).
- dockerfile owns the key (form value wins, stale value scrubbed on clear).
- image defaults to blue-green; dockerfile/static default to recreate;
static surfaces a caveat that storage-backed Deno sites fall back to
recreate. Compose has no selector (recreate-only, blue-green rejected).
i18n apps.new.deployStrategy.* added to en+ru (parity 1750/1750). Extends
sourceForms.test.ts with seed/conditional-emit/owned-key/round-trip cases.
Verified: svelte-check 0 errors, 26/26 unit tests, build green.
