/**
 * One component for every V2 logo. The envelope sends a single `{ guid, fallback_guid?, alt? }`
 * object whose prefix says what it is; this maps it onto the mxui component's props and renders
 * nothing — never a guess — for anything else (`PARENT-ENTITY`, an `ACT-`/`BGT-` guid, an empty guid).
 *
 * The fallback chain is mxui's, not ours: asset for `guid` → category tile for `fallback_guid`
 * (`MerchantLogo`'s `categoryGuid`, applied only when it is a `CAT-` guid because a category tile is
 * the only fallback `MerchantLogo` has) → `alt`. Nothing here probes whether an asset exists.
 *
 * Categories are walked up to their top-level parent before reaching mxui: `CategoryIcon` only knows
 * the top-level guids and silently shows the Uncategorized glyph for a sub-category (identity until
 * categories load). That applies to a `CAT-` logo and to a merchant's `fallback_guid` alike.
