feat(templates): accepted final editorial designs and bounded viewer growth

+## Accepted final editorial templates — Astra integration
+
+Adopts the accepted Astra Daily Digest newspaper, Interview Notes quote spread, Case Study evidence
+ledger and Launch Announcement dark/light poster. The immutable original batch is
+`aa-template-revamp-1788686289312/batch-01-editorial/`; rejected inherited-Sol material is not adopted.
+The first fifteen redesigned templates remain unchanged. This is a separate final integration PR,
+not deployment authorization; all nineteen are only live after the later reviewed rollout.
+
+Daily and Interview are exact accepted source files. Case adds one first-line, file-local
+`noRedundantRoles` compatibility directive. Launch adds one **element-local** `useSemanticElements`
+directive immediately before its existing named CODE region. Nothing else in any template changes:
+CSS, titles, body elements, roles, scopes, IDs, links, SVG, meters and command descendants are exact.
+Canonical SHA-256:
+- Daily: `500f1619164f01ec4aa19a6c1e00277696b50cf3a711463800b22f128a010129`
+- Interview: `146ebab1a80f985196bf788ad5d7ab4fc564dec5c72ec0c4f7b9df154a2a9691`
+- Case: `bda5f8984424f791f6707dc0565c198a6607fcd98f41d851eaed001e2151b007`
+- Launch: `c50f7b44e6e2193126e085fa2b3d3b89266d5dfbb5760dd11633de51fd26fa19`
+
+Case's explicit inventory is one table, seven rows, four columnheaders and twenty-one cells. Four
+native `th scope="col"` headers continue to associate by column with five complete value/meter rows;
+the footer cell spans four columns. The exception is bounded by regression assertions, not permission
+for future unrelated roles. [MDN's display accessibility note](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Properties/display#tables)
+warns that changing table display can affect accessibility in some browsers. Launch preserves its
+one named CODE scrolling region and native Chromium keyboard behavior. No other rule suppression or
+global configuration change is authorized. Eight paired sandbox PNGs/accessibility trees and native
+relationships match the accepted candidates; Chromium evidence does not certify Safari/Firefox or
+screen-reader navigation.
+
+Original content parity accounts for307 text nodes,303 retained after four already-approved decorative
+quote-mark removals in Interview, and170 numeric occurrences. All substantive text and keyed story,
+quote, ledger, feature and availability records remain; code/SVG/meter/link data are exact. No factual
+correction is invented for Case's existing baseline-period wording. Integration adds no content delta.
+Canonical thumbnails use the unchanged generator: Daily1600, Interview1440, Case1280, Launch1440.
+Descriptions name the actual compositions; no other PNG or catalog contract changes.
+
+### Explicitly approved viewer runtime exception
+
+The required twelve-story Daily fixture exposed the existing12000px auto-height ceiling through the
+real locally published artifact viewer, reporter and opaque sandbox. At390px it measures11456px
+closed and12316px with the six-item archive open; at320px,13757px and14745px. Previously the outer frame
+stopped at12000px (all content remained reachable through nested scrolling). The template is not
+shortened or redesigned to conceal this runtime limit.
+
+Only `src/ui/client/viewer.js` changes: `FRAME_MAX_HEIGHT`12000→32768 and its explanatory comment,
+retiring obsolete approximately3000px template-budget advice. Exact approved source SHA-256:
+`43142918625f52d55ac08c0659dcc3eb05e286cf4637199636ac33e391bc1cd4`. This is a bounded operating choice
+with headroom above the14745px fixture, **not** a universal maximum, future-proof promise or browser
+resource-safety proof; the previous test's permissive40000 upper bound is not its justification.
+Matched sender, message type, finite/positive checks, rounding,48px floor and nested-scroll fallback
+remain unchanged. No reporter, CSP, origin, sandbox permissions, dependencies or external assets change.
+
+Regression tests use the actual built repository asset, never a substituted green candidate. The
+Daily open/close test fails before at320/390 and passes afterward, with all twelve stories, six archive
+entries, reachable footer and stable closed/open/closed sizes. The unit test now asserts32768 exactly.
+Existing nine guard controls remain; added at/just-above boundary and real65536px synthetic content
+prove clamping plus usable keyboard/nested scrolling. Ordinary80→160→24px content tests resizing and
+the48px floor. A separate fresh two-origin cloud-mode proof checks byte-exact served viewer asset,
+real published fixture source, both phone widths and settled message counts. No production fixtures.
+
+Lint:34 errors→0 via only the two comments.41warnings comprise40 exact prior warnings and one Case
+mobile `.l-chg display:grid!important` override that preserves the selected grid against generic cell
+`display:block`. It is inventoried, not rewritten merely to quiet warnings. New unit assertions cover
+the two bounded exceptions; browser tests protect native associations, exact data-meter rows, Launch
+keyboard scrolling and the real viewer. Existing tests/frameworks are extended, not replaced.
+
+[Final integrated review](https://anacreon.ai/downloads/aa-template-revamp-1788686289312/integrated-batch01/final/index.html)
+separates fresh final checks, applied-asset viewer proof and final sandbox checks from reused,
+unchanged-source16main/48boundary/no-JS/growth/contrast/fallback evidence. Private fixture databases,
+authentication, logs and backup material are excluded. No analytics, customer/financial data,
+launch, billing, schema, infrastructure or unrelated runtime behavior changes.
