/* Shared frame for project pages (/etchqr/, /registermitra/, ...).

   Every project page gets the same top bar, type, spacing, buttons and footer, so it
   always reads as part of spidey.in. What makes each page its own is set by the page:
   it overrides the colour and shape tokens below with the project's real ones and
   brings its own section layouts. No web or spider motifs here; those belong to the
   homepage. */
