/*
  sitemapmaker — visual identity

  Palette:
    --ink:        #0b0d0c   (near-black base, slight green cast — old terminal glass)
    --ink-raised: #12160f
    --line:       #21281d
    --paper:      #dfe6d4   (phosphor off-white)
    --paper-dim:  #8fa085
    --signal:     #7ef2a3   (crawl signal green — nodes lighting up)
    --alert:      #f2905a   (warm amber for warnings, not red — nothing here is a crisis)
    --wire:       #35422f

  Type:
    Display/mono: 'JetBrains Mono' — the whole UI is monospace, like a crawl log.
    No separate body face; this is a tool, not a magazine.

  Signature element:
    The live node-graph map — every crawled page appears as a lit node,
    connected by a wire to the page that linked it. The sitemap draws itself
    in real time as the literal artifact of what the tool does.
