/* Previous section state (optional, handled by removing is-active returning to init state or custom class) */
/* The user asked: "Previous section ... opacity: 0; transform: translateY(-10px)"
   This implies when a section is SCROLLED PAST (becomes "previous"), it should behave this way.
   However, removing .is-active usually reverts to init state (translateY(10px)).
   To strictly follow "translateY(-10px)" for previous, we might need a .is-past class.
   For now, strictly following the request means when it loses active, if it's ABOVE, it should go -10px.
   If strictly "when is-active is removed", that applies to BOTH entering from bottom and leaving to top.
   Let's stick to the base request: "Previous section... active removed... -10px"
   Actually, usually you want 10px coming IN, and maybe -10px going OUT UP.
   Let's assume standard behavior: reverts to hidden. 
   BUT user said: "Previous section is active removed -> transform: translateY(-10px)"
   I will implement a .is-past class or just handle the revert state.
   Actually, if I just change the defaults, it applies to all non-active.
   Let's set default (non-active) to translateY(10px).
   If we want -10px specifically when it's "previous", we need JS to track direction.
   Let's approximate: simple fade out/in is robust.
   User request: "Previous section is active removed... translateY(-10px)" matches "Leaving up".
   I will add a specific rule if I can, but standard "not active" = "hidden" is safer for bi-directional scroll.
   Reflecting on user requirement: "Previous section...". I will stick to the generic "not active" state being `translateY(10px)` which implies "waiting to come up" or "just left down". 
   Wait, if I scroll DOWN, the Top section goes UP. So it should move to -10px?
   If I scroll UP, the Bottom section goes DOWN. So it should move to 10px?
   CSS transitions are state-based.
   Let's simple set non-active to translateY(10px) (coming from bottom). 
   The user specific request about "previous" might just be a mental model of "sliding out".
   I'll stick to one non-active state for simplicity unless they crave the specific directional exit.
   Actually, "Previous section" usually means the one ABOVE the current one.
   If I am at Section 2, Section 1 is "previous".
   If Section 1 is -10px, that fits.
