   frontier.css — the design language of me·gad·ev
   plan frontier-megadev-261028 · cut W1-1-tokens-monaspace (brief W1-A)

   One stylesheet, one type family, no network. Three sources, each named:

   [mega]   https://mega.dev public CSS, fetched 2026-10-28
            (/_next/static/immutable/chunks/*.css, :root block). Taken: the
            black ladder 050505 / 0a0a0a / 101010 / 1b1b1b / 2f2f2f, ink
            f2f2ee / d9d9d4 / a6a6af, red accent, blue 1px grid, 42.5rem
            measure, .08em label tracking, ease cubic-bezier(.23,1,.32,1).
   [quantum] quantum-replit static/css/styles.css @ e3daa19 (read-only donor).
            Taken: 2px scanline overlay (l.180), step-end cursor blink
            (l.439), phosphor green, the BIOS/POST rhetoric of a gate.
   [mona]   Monaspace v1.400 static webfonts, github.com/githubnext/monaspace,
            OFL-1.1, see fonts/LICENSE-monaspace.txt for sha256 of each file.
            Neon = body + code, Xenon Bold = display.

   Why Xenon: mega.dev sets headings in a serif (Argent Pixel → Georgia).
   Xenon is Monaspace's slab-serif cut, so headings keep that serif nod
   while the whole page stays on one monospaced grid.

   Layers: 1 faces · 2 tokens · 3 legacy aliases · 4 base · 5 layout
           6 components · 7 BIOS motifs · 8 motion + a11y
