/* Ashraellen — GAS book-detail page type
   One shared stylesheet for every language version at /xx/books/monolith/gas/.
   No dependency on books.css, no page-local <style>, no inline style="" attributes.
   GAS is its own page type, structurally distinct from BETON/SLUDGE: it keeps its
   own gas-prefixed / registry-prefixed class system and its own Registry of
   Meanings section — these are not aligned to BETON/SLUDGE naming for the sake of sameness.
   Typography for narrative content follows tokens.css roles (body / lead / accent /
   kicker / registry).
