Carry the design system's explanations from Rastrillo: the exporter and its tests

Human

Prompt

Task 2 of Fiesta part 3, phase A: the design system's explanations, carried over from Rastrillo's gallery. Write the exporter and run it, write prose.json and the review queue, draft the replacements, write the tests against a Render that ignores prose, and send the queue to copy review.

From this commit's own message. The prompt ledger has no entries for it — which is what a squashed, rebased or amended commit looks like, and what every commit looks like in a repo without a ledger.

Summary

hack/seed/run-prose.sh runs a second exporter, hack/seed/_rastrillo/prose_fiestaseed_test.go, in a scratch rastrillo worktree at the seed commit: it reads the family tables, idiom blurbs, shell views, format and screen docs and the two idiom rules, maps each onto Fiesta's examples through examples.json and sources.json, and writes examples/prose.json and the review queue hack/seed/prose-review.json. A string is queued when it names something Fiesta does not have or is not true of Fiesta's HTML. internal/gallery/prose.go loads the file; prose_test.go holds the ten tests, red until Render shows the prose.
Agent notes
prose.json and prose-review.json are not in this commit: 54 of their 148 slots wait on copy review, and the approved text goes into the exporter's approvedProse table so a reseed reproduces it. The ten tests in prose_test.go are red on purpose until the next commit renders the prose; the rest of the plain suite is green. Two family headings will change when the prose titles render: Primitives becomes UI primitives and Formats becomes Dates, numbers and names, both rastrillo's approved wording.

+// The Fiesta prose exporter for internal/designsystem. hack/seed/run-prose.sh
+// copies this file into a scratch rastrillo worktree at the seed commit
+// and runs TestFiestaProse there, so it reads the gallery's English
+// where it is written: the family tables, the idiom blurbs, the shell
+// views, the format and screen docs, and the two idiom rules. It
+// reads, under FIESTA_SEED_OUT, the committed examples/examples.json
+// and hack/seed/sources.json, and writes two files there:
+//
+// - examples/prose.json, every explanation the gallery shows, keyed
+// by family, example and state;
+// - hack/seed/prose-review.json, the strings that could not carry
+// verbatim, each with the rastrillo text, the reason, and the
+// approved replacement once there is one.
+//
+// A string joins the review queue when it mentions something Fiesta
+// does not have (a Go template, a partial, a server, a cookie,
+// rastrillo itself) or when, read against Fiesta's HTML, it is not
+// true. The mechanical part is proseWords and proseFields; the rest is
+// a judgement, written down in proseUntrue with its reason. A queued
+// string's slot in prose.json is empty until approvedProse carries
+// its replacement, so a reseed reproduces the approved text and never
+// the rastrillo one.
