The three pages had each grown their own tokens, type scale and alignment, so the openings looked like three different sites. The document shell now owns the masthead family - tokens, centred masthead, eyebrow, title, lede, fact strip, scroll cue and the index component - and the pages carry only their content. The Mirror gains the section index the arc has, drops its duplicate technical footer, and its title now uses the same magenta accent instead of a one-off gradient.
