/**
 * System-prompt generator for an A2UI catalog. Renders the agent-facing catalog
 * description straight from the catalog's registry, so the prompt and the
 * validator can never drift (a drift-guard test asserts every component and enum
 * value is covered). Pure TS, no Svelte — a server building the prompt has no
 * DOM, and this module never imports catalog VALUE code from `urbicon/` (the
 * caller passes the spec), so it stays out of the Basic bundle.
 *
 * With no options the output is the Basic-catalog prompt, byte-identical to
 * before the catalog refactor. Pass `catalog` to render a richer catalog: when
 * its specs carry categories / shared axes (the Urbicon catalog), the prompt
 * grows a "Shared axes" section, groups components by category, compresses
 * shared-axis props, and adds catalog-specific don'ts — all gated on features
 * the Basic catalog does not have, so the default stays untouched.
 *
 * Deliberately excludes any TRANSPORT section (how envelopes reach the client)
 * and any data-schema section: those are app-specific and each app appends them
 * (the chat-demo appends its fenced `a2ui` protocol + `a2uiDataSchemaSection`).
