   subsidy-styles.css — the Block Subsidy portal layer.
   Reuses tokens + most language from explainer/styles.css and showcase/sc-styles.css
   (--itc cyan, --btc orange, glass cards, sc-section / sc-kicker / sc-h / sc-sub,
   chart-wrap, deck, btn-itc/btc). Adds only the subsidy-specific UI: the lifetime
   scrubber, the four-phase ribbon, the big reward readout, the supply counter,
   the "truth" reveal cards, and the real-source code block.
