- Around line 19-25: The HTML currently includes the development React scripts
(react.development.js and react-dom.development.js); for production deploys
replace those script tags with the production builds (react.production.min.js
and react-dom.production.min.js) or conditionally load production URLs when
NODE_ENV is "production" so users do not serve the development bundle; update
the script src attributes (or add a small inline environment check) to reference
the minified production files from the CDN (and keep `@babel/standalone` only for
dev if you remove it in production).
- Around line 795-797: The difficulty badge text ("Medium") inside the span
element with className "bg-purple-700 text-white text-sm font-bold px-3 py-1
rounded-full" is inconsistent with the file path and folder (Easy/Halloween
party); update the badge text to "Easy" (or alternatively move the file to a
Medium folder) so the displayed difficulty matches the file location—modify the
span's inner text to "Easy" to resolve the mismatch.

- Around line 325-342: The file places "from __future__ import annotations"
after "import sys", which is a syntax error; move the future import to the top
of the module (before any other imports or code, except module
docstring/comments) so the statement appears before "import sys" and any usage
(keeping the function halloweenParty and variables like input_data/int parsing
unchanged).

の適切な場所に移動して両者を一致させてください。

- Around line 1133-1135: The progress text using className "text-slate-600" (the
<p> showing "{activeStep} / {stepsData.length}") may have low contrast on dark
backgrounds; update that class to a lighter slate variant such as
"text-slate-400" or "text-slate-300" (or a token that meets WCAG contrast) and
verify the change in the component rendering to ensure sufficient contrast
across themes.
- Around line 239-241: The page uses a <script type="text/babel"> block with
React hooks (useState, useEffect, useRef) and many JSX attributes (className,
onClick, etc.) but Babel standalone isn't loaded, so the browser can't transpile
JSX; fix by either (A) adding the Babel standalone loader before this script
(load https://unpkg.com/@babel/standalone/babel.min.js) so the JSX block runs
as-is, or (B) fully precompile the JSX to plain JS (React.createElement) using
your build tool and replace the <script type="text/babel"> block with the
transpiled <script> output (or change type to text/javascript) so
useState/useEffect code runs without runtime transpilation.

party/Halloween_party.html:
- Around line 1827-1830: The I/O description ("sys.stdin.buffer 一括読み込み") doesn't
match the actual example code which uses input().strip(); update either the
explanatory text or the sample code to be consistent: either change the list
entry ('sys.stdin.buffer 一括読み込み') to describe line-based input via
input().strip(), or replace the sample code's input() usage with a buffered read
implementation (using sys.stdin.buffer.read()/read().splitlines() and
appropriate decoding) so that the displayed code and the phrase in the list (and
any related labels like 'I/O（最適化版）') refer to the same approach.
- Around line 240-241: 現在の <script type="text/babel"> ブロック（中で useState /
useEffect / useRef を使い、JSX の className を含む）をブラウザで実行するには Babel Standalone
が必要です。修正するには、このスクリプトの直前に Babel Standalone
を読み込むタグ（https://unpkg.com/@babel/standalone/babel.min.js 等）を追加するか、代替として JSX
を取り除き普通の ESモジュール/トランスパイル済みスクリプトに変換して <script type="text/javascript">
に変更してください；基本的には現在の <script type="text/babel"> をそのまま使う場合は必ず Babel
スクリプトを先に読み込むようにしてください（参照箇所: <script
type="text/babel">、useState/useEffect/useRef、JSX の className、#root マウント部分）。

- Around line 45-47: The page forces smooth scrolling and other animations
without respecting users' motion preferences; wrap the global rule "html {
scroll-behavior: smooth; }" and any animation/transition rules (the block around
lines 82-98) with a prefers-reduced-motion override so that users who set
reduced motion get non-animated fallbacks (e.g., set scroll-behavior to auto and
remove/disable transitions/animations using `@media` (prefers-reduced-motion:
reduce) targeting the same selectors); update or add the corresponding
media-query override for all instances of scroll-behavior and any CSS
animation/transition declarations to ensure they are disabled for reduced-motion
users.
- Around line 388-421: The diagram shows two vertical dashed lines (<line
x1="70" .../> and <line x1="130" .../>) but the label text element currently
reads "v=3本 垂直"; add a third vertical dashed line matching the others (same
stroke, strokeWidth, strokeDasharray) between x=70 and x=130 (e.g., x1/x2="100")
so there are three vertical cuts to match the label, and adjust any nearby label
positions if needed to avoid overlap (refer to the existing <line> elements and
the <text> element containing "v=3本 垂直").

In @.agent/skills/spec-driven-development/SKILL.md:
- Around line 15-17: The SDD phase lists use inconsistent rule path notation:
replace the occurrence of ".agent/rules.md" with the directory-style
".agent/rules/*.md" (or vice versa if you prefer directory listing) so all
references match; update every SDD-phase entry in SKILL.md that mentions the
rules (the entries currently containing ".agent/rules.md" and the later
".agent/rules/*.md") to use the same notation consistently.

In `@Mathematics/Fundamentals/HackerRank/Claude/Easy/Halloween`
party/Halloween_party.html:
- Around line 147-154: The stylesheet lacks base/background and font definitions
causing low contrast and missing fonts; update global/base styles to set a
readable page background and default text color (targeting body), add a card
background and padding/border-radius for the .card element and ensure .card-glow
has sufficient contrast (darker translucent backdrop or lighter text) to meet
readability, and define the .mono and .outfit classes with the intended
font-family fallbacks so the correct fonts are applied; adjust only the
selectors .card-glow, .card, body, .mono, and .outfit to restore contrast and
typography.
- Around line 217-218: ページに生のBabelランタイムを読み込むスクリプトタグが残っており（<script
src="https://unpkg.com/@babel/standalone/babel.min.js"></script> と <script
type="text/babel">）、本番配信の初回表示コストとCSPの問題を引き起こすため、ソースを事前にトランスパイルして配布用バンドルに置き換えてください:
開発中のJS/JSXをビルド（例: babel/webpack/tsc等）して生成されたトランスパイル済みファイルを読み込むようにし、該当の <script
src="https://unpkg.com/@babel/standalone/babel.min.js"></script> を削除し、元の <script
type="text/babel"> を type="text/javascript"（または省略）とし src属性でビルド済みバンドル（例:
bundle.js）を指定することでランタイム依存を排除してください。
- Around line 17-43: The external CDNs (Tailwind, React, ReactDOM, Prism.js and
related plugins) are included without SRI/locked versions; update the script and
link tags that load these resources (e.g., the Tailwind <script>, React/ReactDOM
<script> tags, and Prism <link>/<script> tags referenced in the block) to use
exact versioned URLs and add integrity attributes plus crossorigin="anonymous"
for each resource; fetch the correct integrity hashes for the exact versions you
pin and replace the current unpinned URLs so every external resource has both a
fixed version and a matching integrity="" and crossorigin="anonymous" attribute.

party/Halloween_party.html:
- Around line 1137-1139: The footer element rendering the version string (the
<footer className="text-center text-slate-600 text-xs py-8"> block that contains
"Python 3.13.3 解説 🎃") should be updated to match the repository's
.python-version (3.12.11); change the displayed version text from "Python
3.13.3" to "Python 3.12.11" (or ideally reference a shared version constant if
one exists) so the footer's Python version is consistent with the repo standard.
- Around line 217-218: The page currently includes a runtime Babel transpiler
and an inline script using type="text/babel" (see the script tag referencing
"/vendor/babel/babel.min.js" and the script with type="text/babel"); remove the
runtime transpile by precompiling JSX/ESNext into production JS and replace
these tags with a reference to the compiled bundle (e.g., a built .js artifact),
and remove the Babel vendor include and the type="text/babel" attribute; update
the build pipeline (Babel/webpack/rollup) to output the production script used
by the page and ensure the HTML references that compiled file instead of
performing client-side transpilation.

- Line 17: Update the workflow path notation to be consistent by replacing the
bare "workflows/" reference with ".agent/workflows/" in the SKILL.md content
(specifically change the occurrence "workflows/" in the Execution step to
".agent/workflows/") so it matches the other reference ".agent/workflows/" and
avoids documentation confusion.

- Around line 147-154: The .card-glow rule currently only sets text color which
can break readability on varying backgrounds; update the CSS for both body and
.card-glow (and any duplicated .card-glow rules at 189 and ~783) to include at
minimum a contrasting background-color and a subtle border or box-shadow (e.g.,
light/dark background depending on theme) so text remains legible, and ensure
.card-glow * still inherits color; modify the body selector to provide a default
page background and contrast baseline, and add border/border-radius or
box-shadow to .card-glow to visually separate the card from the page.
- Around line 68-75: The prefers-reduced-motion block only hides .particle but
doesn't disable transitions/animations/transforms used elsewhere; update the
`@media` (prefers-reduced-motion: reduce) section to also override all
motion-related properties for particles and their interactive states by adding
rules such as .particle, .particle * { animation: none !important; transition:
none !important; transform: none !important; will-change: auto !important; } and
also disable hover/focus effects with .particle:hover, .particle:focus {
transform: none !important; } (or more generally .particle, .particle *
including pseudo-classes) so the hover/transform/transition rules defined around
the blocks covering lines ~77-97 and ~176-186 are effectively disabled under
reduced-motion.
