Slide Timing Rules

Timing in Taleem is explicit and declarative.

All timing values describe when something becomes visible. Nothing is inferred.

Slide-Level Timing

Every slide defines a visible time window.

{
  "start": 10,
  "end": 20
}

A slide is considered visible when:

start ≤ currentTime < end

Item-Level Timing (showAt)

Items inside a slide may define showAt.

{
  "name": "bullet",
  "content": "Key point",
  "showAt": 12
}

An item is visible when:

currentTime ≥ showAt

No Implicit Ordering

Item order does not control timing.

Only explicit time values matter.

Browser vs Player

Timing rules exist even if they are not used.

• Browser Engine ignores time
• Player Engine enforces time

What Timing Does NOT Do

• animate content
• create transitions
• resolve overlaps
• fix invalid ranges

Timing is a contract, not behavior.

Authoring Rule

If something appears later, it must say when.
