/* fenix-tailwind-shim.css
 * TAILWIND-SHIM sub-plan — Tailwind 3.4 vocab, version-locked.
 *
 * Implements the bounded utility set Fenix renderers may emit (TAILWIND-VOCAB rule):
 *   spacing / layout / grid / typography-size / object-fit / border-radius (~40 utilities)
 *
 * For themes that don't bundle Tailwind themselves. Theme adapters declaring
 * IsTailwindNative=false get this auto-injected by the public render pipeline.
 *
 * ALLOWED utilities (renderers may emit these):
 *   m-{0..16}, mx-auto, my-{0..16}, mt-{0..16}, mb-{0..16}, ml-{0..8}, mr-{0..8}
 *   p-{0..16}, px-{0..8}, py-{0..16}
 *   max-w-{sm,md,lg,xl,2xl,3xl,4xl,5xl,6xl,full}, w-full, h-full
 *   flex, inline-flex, grid, items-{start,center,end,baseline}
 *   justify-{start,center,end,between,around}, gap-{0..16}, flex-{col,row,wrap}
 *   block, inline-block, hidden, md:{block,grid,flex,hidden,grid-cols-1..4}
 *   text-{xs,sm,base,lg,xl,2xl,3xl,4xl,5xl,6xl}, text-{left,center,right}
 *   font-{normal,medium,semibold,bold,extrabold}, italic
 *   leading-{none,tight,snug,normal,relaxed,loose}, tracking-{tight,normal,wide,wider}
 *   object-{cover,contain}, aspect-{square,video}
 *   rounded-{none,sm,md,lg,xl,2xl,3xl,full}, border, border-{0,1,2,4}
 *
 * FORBIDDEN (renderers must NOT emit these):
 *   colour utilities (text-slate-*, bg-pink-*) — use CSS vars
 *   shadow / gradient / hover / transition / ring utilities — use BEM hooks
