 The title page's scroll dim is a draw-only colour overlay, not an alpha-animated full-screen layer. Discover scrolls its backdrop through placement offsets rather than a full-screen translation layer. Initial loading animated layers are Home **2**, Library **up to 3** lazy rows, Discover **2**, title header **1**, person **2**; pending title episode/cast shelves add **1 each**, and each pending Discover lane owns **1**. Deep Home loading is bounded to **4** visible shelf layers. These are animated layers, not independent pulse clocks or every static display-list node: one shared pulse clock drives the loading screen without adding a layer. An ordinary hero hand-off animates **3** bounded owners (outgoing art and two copy blocks) above an opaque artwork base. Interruptions retain the painted composite without resetting alpha; each outgoing owner keeps its own original 320 ms artwork / 200 ms copy lifetime rather than restarting with later presses. Focus changes can animate **2** card transforms, **1** caption and at most **2** rating plates; ordinary artwork fades are painter draws without additional compositing layers. Late title metadata adds at most **4** bounded alpha layers: title ratings, play-target ratings, genres and overview. No animated owner is full-screen.
 
-The series readiness band reserves **56 px (28 dp)** from its first content paint, including when empty or when readiness later disappears. Ratings remain inside the fixed-height facts band. The series header's measured height therefore cannot change when late ratings/readiness arrive; overview, actions, season and episode anchors retain their coordinates. Skeletons have no click/hover focus targets; pending episode/cast rows remain absent from the key-navigation state until real cards exist. Initial title/person loading retains destination focus rather than focusing the root nav; Down cannot enter a skeleton, and Back still pops the route without opening the picker. An already-ready catalogue or held title stays Ready while a same-route, same-person refresh reads new data; the existing signed-in authentication guard remains authoritative, and loaded copy/rows do not remount or replay their entry motion.
+The approved title follow-up (2026-11-07) supersedes the fixed readiness reservation: an absent readiness line occupies **0 px**, while a present line occupies **56 px (28 dp)**. Late arrival/removal animates that height over the **200 ms late-line duration with token ease-out**; reduced motion snaps. Overview, actions and following rows move monotonically with that band; an already-pinned focused row stays pinned through same-remeasure scroll compensation. Ratings remain inside the fixed-height facts band and appear once: an explicit episode page uses its opened episode's own set, including the episode score, rather than the series-only set. Series and episode pages have no redundant Seasons shortcut; Down reaches the season chips. Skeletons have no click/hover focus targets; pending episode/cast rows remain absent from the key-navigation state until real cards exist. Initial title/person loading retains destination focus rather than focusing the root nav; Down cannot enter a skeleton, and Back still pops the route without opening the picker. An already-ready catalogue or held title stays Ready while a same-route, same-person refresh reads new data; the existing signed-in authentication guard remains authoritative, and loaded copy/rows do not remount or replay their entry motion.
 
 Discover key traversal skips pending lanes in both directions. If every remaining lane is pending, Down stays on the real filter chips and Back returns to nav; a skeleton must never create an empty-column focus range.
