/*
 * FYRKA shared in-game HUD
 * ------------------------
 * ONE minimal, non-overlapping heads-up display for every FYRKA game.
 *
 * Rules of the house (extracted from game_01, the reference HUD):
 *   - The HUD is a compact translucent rail parked TOP-LEFT.
 *   - The top-right stays clear for the FYRKA badge (shell launcher).
 *   - The bottom stays clear for the touch controls (joystick + buttons).
 *   - Everything is pointer-events:none so it never eats a tap.
 *   - On phones only the CORE live stats survive; anything tagged
 *     [data-hud="secondary"] (level, score, credits, district, upgrades,
 *     objective prose …) is hidden — it lives in the central FYRKA menu.
 *
 * A game reskins the whole HUD by overriding just --fh-accent (and, if it
 * wants, --fh-bg) on the .fyrka-hud root. Everything else derives from tokens.
 *
 * Class contract:
 *   .fyrka-hud                 fixed top-left rail (put it on the HUD root)
 *   .fyrka-hud__stat           one compact cell (label + value and/or bar)
 *     .fyrka-hud__label        small uppercase caption
 *     .fyrka-hud__value        the number/text
 *     .fyrka-hud__bar > i      a fill bar (set inline width on the <i>)
 *   .fyrka-hud__objective      compact one-line mission/objective chip
 *     .fyrka-hud__objective-text   prose (auto-hidden on phones)
 *   [data-hud="secondary"]     drop this element on phones / coarse pointers
