===========================================================================
このファイルの使い方（アクアリウムマスター固定ページ）
===========================================================================

【置き場所】
WordPressで固定ページを1つ作り、スラッグを aqua-master にして
上の 〜 を本文へ貼る。
（URL：https://learn.futabajuku.jp/aqua-master/
プラグイン側の定数 AQUA_MASTER_JSON_URL と一致させる）

推し活マスターとまったく同じ方式です。

【固定ページを作らなくても動きます】
ページが無い場合は、プラグインに組み込んだ初期データ（魚16種・背景5種）で
動作します。まずはそのまま使い、素材ができてから差し替えられます。

【魚（fish）の項目】
id 必須。半角英数字とアンダースコアの一意なID。
※ すでに配布したあとで id を変えると、利用者が持っている
その魚が水槽から消えます（所持データ自体は残ります）。
name 必須。画面に出る魚名。
image 横向きの魚画像URL（WordPressのメディアにアップしたURL）。
空欄のときは組み込みのSVGシルエットで表示します。
image2 任意。口を開いた・ヒレを動かした状態などの第2画像。
設定するとCSSがときどき切り替えます。空欄なら切り替えません。
size "small" / "medium" / "large"
中単元テスト＝small、大単元テスト＝medium、学年総合問題＝large
のクリアで獲得できます。
zone "surface"（水面付近）/ "middle"（中層）/ "bottom"（底付近）
bottom の魚は自動的に「底物の動き」（移動量・上下動が少なく、
止まっている時間が長い）になります。
speed 水槽を1往復する秒数の目安。大きいほどゆっくり泳ぎます。
個体ごとに ±20% 程度ばらつきます。
scale 表示倍率。1が標準。水槽の高さに対する比で計算するため、
ミニ水槽でも全画面でも同じバランスになります。
facing 画像の向き。頭が右なら "right"、頭が左なら "left"。
省略時は "right" です。ここを間違えると魚が後ろ向きに泳ぎます。
shape 画像を使わないときのシルエットの形。
"fish"（一般的な魚）/ "disc"（体高のある魚）/
"long"（細長い魚）/ "catfish"（ナマズ系）/ "shrimp"（エビ）
color シルエットの体色。color2 はヒレ・尾の色。
image を設定した魚では使われません。

※ fish を1件でも書くと、組み込みの16種はすべて置き換わります。
一部だけ差し替えたい場合も、使いたい魚を全部書いてください。

【背景（backgrounds）の項目】
id 必須。一意なID。
name 編集画面に出る名前。
image 背景画像URL。設定するとこれが優先されます。
css 画像を使わないときの背景（CSSのグラデーション等）。
deep ダークモード時の背景。省略すると css をそのまま使います。

背景はすべて最初から使用可能で、学習報酬にはなりません。

【上限とポイント】
limits 生息域ごとに水槽へ入れられるポイントの上限。
points サイズごとの消費ポイント。
例：中層の上限10・Sサイズ1ptなら、中層にSサイズを10匹入れられます。
数を増やしたい／減らしたいときはここだけ変えてください。

【初回プレゼント】
firstGiftFishId 初めてアクアリウムモードを開いたときに1匹だけもらえる魚のID。
fish の中に存在するIDを指定してください
