SlotText changelog

2026-09-21: Unified the usage guide, source property table, and Site / AI reading entry points. Documentation only; component behavior is unchanged.

motionColor now covers every target character. Retained characters and formatting marks also join the unified per-character color return sequence; the full timing follows TextMotionSpec §2.1.
Character-change effects retain their existing rules. Without a color setting, with animation disabled where applicable, or when reduced motion applies, the final original color is shown. Continuous updates reschedule the color sequence, and unmounting cleans up color animations.

Continuous updates now continue from the current slot appearance, retaining movement already in progress while reducing per-character timers and repeated layout reads. interrupt=false still waits for the current playback to finish before applying the latest target.

Moved SlotText-specific isTail handling ahead of shared LCP / LCS: old characters beyond the new text length are extracted by original index before the remaining characters use shared reassembly.

Completed the isTail end-deletion rule from slot-text-main: old characters beyond the new text length use 0.75 times the duration and join the exit wave from the middle of the line.

The default exit direction changed to upward, matching NumericText’s default text direction.
Character entrance and exit gained the same opacity changes as NumericText: 0 -> 1 on entrance and 1 -> 0 on exit.

Adopted the shared timeline used by NumericText, unifying natural-width commits, retained-character FLIP, and changed-character entrance/exit at the same reassembly point. This fixes width changes squeezing characters that have not exited yet.
Layout FLIP no longer adds exitOffset. Ordinary-text stagger now follows local ordering in the changed middle span, preventing long prefixes from delaying entrance and exit.

Recreated SlotText from slot-text-main: default direction changed to down, with interrupt=true and playOnMount=false by default, and 45ms stagger and wobble restored. Character processing moved to the LCP / LCS + FLIP shared with NumericText; SlotText retains only the vertical slot-scroll appearance.
replayKey now triggers whole-line replay only when text is unchanged. Normal text changes preserve unchanged characters as in the reference project.
Added TextMotion-Demo Slow Mode support through transition overrides and tightened mixed-content detection so ordinary text containing digits does not accidentally use right-to-left numeric ordering.

motionColor now defaults to undefined, leaving text color unchanged unless explicitly set.

Added numeric semantic classification through motionRole for ordinary numbers, timers, and countdowns. Multiplication and division choose Up or Down according to whether the result grows or shrinks.

Numeric trend parsing now handles increasing and decreasing negative numbers plus cyclic timer/countdown comparisons of full time strings. Addition rolls upward; subtraction rolls downward.

At that time, defaults were updated to match the confirmed screenshot: physical upward rolling, stagger=45ms, duration=300ms, bounce=0.6, skipUnchanged=true, and interrupt=false. The interruption policy was superseded by interrupt=true in v1.7.0 to match slot-text-main.
Added numeric-trend semantics through trend: increasing numbers roll up, decreasing numbers roll down, and changed digits start from least to most significant. The direction API was later consolidated around normal / reverse semantics.

Root Frame now enables default Frame motion by default. Internal slot animation runs alongside component-level while* and parent choreography.
