Same rule, new shell: the right column only exists when there is a list for it. The title, status line and page actions (watch, watchlist, favourite) move into the glass header card next to the search field, behind ⋯, as on every other page. Panels are flat base-200 like Home's widgets; glass stays for what floats.

Every season on one page. The S1–S5 pills are a segmented control now: the glass pill slides to the season you pick, which opens in place and scrolls into view on the first click, its header flashing. Skeleton rows while it loads, then episodes fade in one by one. The playing episode uses the app's active pill instead of an outline. Try it: click S4, then an episode.

No new button. Closed, the playlist is a glass rail, the twin of the nav rail on the left: same 84px width, an Episodes item at the top, then Playing, Next and the episode map. Hover it and the list opens over the player as a glass sheet with Discover's exact motion (fades, slides out of the rail and sharpens, its rows following one after another); leave and it closes. Pin in the sheet's header, or a click anywhere empty on that header row, keeps it open: the column grows with the animation you liked, and the pin stays lit; click it again to fold back. On a touch screen: tap the rail to open, tap the dimmed player to close.

Phone: unchanged from B; the list lives in the Episodes tab under the player.
