Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

aurora scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

极光是封面页的梦中情「风」——翠绿、蓝紫、靛蓝的多色渐变融化在模糊里,如北极的夜空中飘动的极光。这个风格天生就是为了封面、CTA和结语页而存在的。它不需要承载大量内容,它只需要让第一眼和最后一眼都美到让人屏住呼吸。

配色

标题 #1e1b4b 深靛、正文 #312e81 靛蓝,强调色 #4f46e5 靛紫与 #06b6d4 青蓝是极光中的两种光。背景 linear-gradient(135deg, #a7f3d0 0%, #6ee7b7 30%, #6366f1 60%, #a855f7 100%) 是翠绿到蓝紫的四段渐变,如极光的色彩。卡片 rgba(255,255,255,0.55) 高度透明,边框 rgba(255,255,255,0.4) 是半透明的白色描边。

排版

现代无衬线字体,标题大且居中,字号可以铺满画面。正文极简,每页不超过两行。文字浮在渐变之上,可以带模糊背景增强可读性。

布局

全屏渐变是布局本身。内容居中,大面积的极光色彩作为背景。不需要传统的卡片布局,让文字直接融入极光中。

动画

blur-in、gradient-flow、shimmer-sweep

适合场景

封面页、CTA 页、结语页、活动开幕——需要让第一眼就惊艳、最后一眼就难忘的场合。

配图

愿景发布、探索主题、科技远景、自然议题和章节开启页,可用极地天空、远山、探测器、孤立建筑或人物剪影中的一个,置于深靛与绿青紫光带中;没有可感知的远景或场景时不要硬加极光。

指标、模型、技术流程、对比、时间线和结论页不配图。

不要

  • 不要用于正文密集的内容页
  • 不要用硬边框或锐利布局
  • 不要让文字量超过极光的美
  • 不要用深色背景破坏极光的梦幻

What ships with it

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
