/*
 * The actual text-editing surface. It sits directly on top of the canvas,
 * fully transparent (both fill and text) except for a visible caret and the
 * browser's own selection highlight — the letters everyone sees are drawn
 * by the canvas underneath. Font size/spacing/line-height/alignment are
 * kept in sync with the canvas layout from JS (see syncTextOverlay in
 * main.js) so clicking into a word and typing lines up with where that
 * word is actually drawn.
 *
 * Deliberately NOT set to Comico here: browsers size the native caret and
 * selection highlight off a font's own ascender/descender metrics rather
 * than the CSS line-height, and Comico's are unusually generous (its
 * ascender+descender adds up to ~1.46x its em-size). A normal system font
 * gives the browser more ordinary metrics to work with for that native
 * chrome, and still gives reasonable width-matching for click-to-position
 * via the font-size/letter-spacing we sync — though caret/selection height
 * still isn't pixel-perfect against the canvas text in every browser, since
 * that native rendering isn't something CSS gets full control over. Typing,
 * clicking, and selecting all work correctly regardless.
