/**
 * HST shell skin for Staticprofit.
 *
 * Ported from the options_limits platform:
 *   series_tools_python/options_limits_backtest/frontend/src/index.css
 *
 * HST is styled as an options_limits "instance": it inherits the platform's blue-500
 * accent and adopts MetricAlgo azzurro (48 190 217) as its instance colour, driving the
 * same gradient/glow system the options frontend uses — top accent bar, body radial glow,
 * sidebar gradient, card glow, cyan highlights.
 *
 * Compatibility contract — every rule is scoped under `body.hst-shell`. Nothing here can
 * reach the metrix, ma_options or seriestrategy shells, and ma_limits_tokens.css is never
 * modified. Loaded only when config('sp_view.hst_modern_theme') is true.
