/*
    Dungeon Dweller - main menu styles.

    Purely presentational, unlike game_styles.css: nothing here is measured or
    read back by JavaScript. src/index.js only toggles the `hidden` attribute on
    the menu and the instructions panel.

    Sizing leans on clamp() against viewport units so the menu scales smoothly
    without breakpoints; the single media query at the foot only widens the
    fixed-width blocks on narrow screens.

    Paths are relative to index.html at the repo root - except the @font-face
    below, which resolves relative to this stylesheet in styles/.
