Mirrors the backend schema additions (StepRowBlock.items.subtitle,
new IconBlock) needed for the /lebensuhr Pages migration: PageBlock
type + mapPayloadPageBlock in payload.ts, a "icon" case in
PageBlocks.tsx, and SYMBOLIC_ICONS (the clock face) added alongside
STEP_ICONS in StepIcons.tsx — a distinct registry since these icons
are standalone, not part of an icon-above-text row.
Pages/getPageBySlug/mapPayloadPage in payload.ts follow the exact
getPostBySlug/mapPayloadPost pattern. PageBlocks.tsx renders a Pages
doc's `layout` field, reusing existing components (RichText,
StepArrow, STEP_ICONS, TestimonialsGrid) rather than reinventing per-
block styling — matches what /lebensuhr, /3x3-system, and
/7-tage-klarheits-check already hand-built. LivePageContent.tsx
mirrors LivePostContent.tsx's live-preview pattern, using a synchronous
subset of the block renderer (testimonialsRef needs an async fetch a
client component can't perform inline, so it's skipped in preview
only — same "editable subset" scope-cut LivePostContent.tsx already
makes). buildWebPageSchema in structuredData.ts is the generic
JSON-LD fallback for content types with no bespoke schema (Article/
Product don't fit a page-builder page).
Verified end-to-end: inserted a real Pages test document (SQL, since
no admin auth available here) covering richTextSection/quote/ctaCard,
confirmed /[slug] renders it correctly, confirmed notFound() after
deleting it, then cleaned up the test row.
