/* Toga.tv, in one stylesheet.
 *
 * The design system is toga-workspaces' (packages/toga-ui and apps/web): the indigo palette, Barlow,
 * pill-shaped controls with a raised shadow, glass surfaces and the indigo footer with rounded top
 * corners. Its tokens are restated here as custom properties because this app has no build step —
 * a stylesheet that needed compiling would be the one thing that did.
 *
 * Superseded (2026-11-07): the app used to be dark gold-on-black (--accent #d4a24c on #101014),
 * a placeholder palette that predates adopting the design system. */
