/*------------------------------------------------------------------------------
CHARACTERS
登場人物の一覧（肖像の額を並べた名簿）と、プロフィール（共通のダイアログ .lv-dialog--full の中身）。
mobile.css / style.css の共通パーツとトークンを前提に、このページ固有のレイアウトだけを定義する。

人物が増えても崩れないよう、一覧は画面幅に合わせて列の数が変わる格子に並べる。
画像がまだ無い人物は、名前の頭文字を置いた仮の肖像（.chara-placeholder）で見せる。
動きは、一覧が一度だけ浮かび上がる（[data-reveal]）のと、プロフィールが現れるときのフェードだけ。

レイアウトの切り替え条件
- 縦長構図（初期値）
- 横長構図: (min-width: 769px) and (orientation: landscape), (min-width: 1200px)
