Restores the 208 catalog items reverted after their previews 404'd in production, this time on the payload mechanism rather than the .html files that caused the outage. The generator no longer writes a preview document to docs/public. That writer, and the machinery under it, existed only to produce files the docs host discards, so it is gone rather than bypassed. Items now embed the composition itself via a payload, which is what the previous change already does for the items that were already in the catalog. The variables explorer is parked, not restored: it drove its preview through the same unpublished .html path, so it would have shown an empty frame. Items that declare variables get the live player plus the static variables table, and reconnecting the explorer to payloads is a follow-up.

line-swap: HyperFrames video primitive (text effects / beat replacement)
|
|
|
|
A masked full-line beat replacement, generalizing flagship frame 01: line_a
|
|
rises into an overflow-hidden mask and holds center, then on the swap beat
|
|
it exits up through the mask as line_b enters bottom-up on the same beat.
|
|
One restrained slam, smooth ease, no overshoot. Optionally an accent
|
|
underline draws left to right beneath underline_word of line_b after it
|
|
lands (scaleX from a left origin, the flagship bar draw).
|
|
|
|
Variables:
|
|
line_a (string): the first line, replaced on the beat.
|
|
line_b (string): the line that lands and holds.
|
|
swap_at (seconds): the beat, relative to mount start. Clamped so line_a
|
|
finishes entering first and line_b plus the underline complete before
|
|
any exit begins.
|
|
underline_word (string): first case-insensitive substring match inside
|
|
line_b gets the underline. Empty or unmatched disables it.
|
|
accent (green | blue | violet): underline color via the contract token map.
|
|
exit (none | fade | up, default none): frame roots own transitions;
|
|
holds end films.
|
|
|
|
Envelope, fixed IN and OUT with elastic HOLD only (never time-scaled):
|
|
IN_A_BASE = 0.50s line_a enters bottom-up through the mask
|
|
SWAP span = 0.72s line_a up-and-out (0.35s) overlapping line_b in
|
|
(starts 0.22s after the beat, lands 0.50s later)
|
|
UL span = 0.60s 0.15s beat after the land, then a 0.45s draw
|
|
(0 when underline_word is empty or unmatched)
|
|
HOLD = max(0, D - phases), completely still
|
|
OUT_BASE = 0s for exit none, otherwise 0.45s
|
|
If D is shorter than the fixed phases, they compress together.
|
|
|
|
Mount contract: the runtime clones only this template. #root fills the host
|
|
box, establishes the container query basis, has no data-width or
|
|
data-height, and registers one paused timeline under the literal
|
|
line-swap key.
