// The public-offer page renderer: splices the live catalog price list into the owner-edited offer

// tables before rendering.

// replaced by pricingTables (the two markdown tables the backend projects from the active catalog),

// in a product title is never read as a replacement pattern; a missing marker leaves the text as is.
