www: ChunkFive for logo/titles; normalize asm references to "GNU asm"

Browse source 
ChunkFive webfont (woff2 + woff, ~43 KB total) dropped into
www/fonts/chunkfive/; style.css adds @font-face with font-display:swap
and applies the family to header h1 (3.2rem logo) and main h2
(1.5rem section titles). Monospace body text unchanged. Font files
reused from www.unturf.com; SIL OFL.

index.html: "x86_64 assembly interpreter" and table-row labels
"Pure x86_64 assembly" / "Assembly + naive mark-sweep GC" now read
"GNU asm" — precise and consistent with how we talk about the tier
elsewhere.

Lumbda is a Lisp/Scheme-derived language with four independently implemented execution backends sharing one surface syntax and one test suite. A Python tree-walker with an optional bytecode VM, a C implementation that adds an x86_64 JIT, and a pure x86_64 assembly interpreter (~6,600 lines of GNU assembler, ~23 KB stripped, zero external dependencies). Every backend runs the same <code>.lsp</code> source byte-identically, with full first-class continuations, exact rationals, records, and hygienic macros.
