Adds motion/stroke-titles to wai/vector-conformance/: a title card and a credit roll, the document the WAI site's /cargo titles card plays.

The document. 1280 × 720 design canvas, one size, 25 fps, 175 frames, in the default stroke set (ASCII):

• Lower third: a bar and two lines that slide in, hold and fade out as a group.
• Credit roll: a heading and five credits, rising three design pixels a frame, then fading.
• Windows: each line's window is cut to the frames at which every run of the line meets the canvas (graphics-vector §5.4, Where a block is), from the outline set's exact glyph boxes and the sink's own track evaluation.

Its words name no person, company, product or place.

Files.

• The generator, in wai-vector/src/vectors/text.rs.
• The payload and its authoring form.
• The expected file, with every frame's digest and the text record's.
• index.json and sha256.json.
• The corpus README's group text and provenance line.
• A CHANGELOG entry.

No existing vector or expected file changes.

Evidence (build host):

check	result
cargo test --locked, debug and release	pass
vectors verify	356 vectors and 14 text records
vectors gen	tree unchanged afterwards
the sink's build without author	builds
the independent checker	370 of 370 expected files byte for byte
build-pkg.sh, then verify.mjs under Node	pass
the three-engine browser harness	0 failures in Chromium 148, WebKit 26.4 and Firefox 150
public names (private list), comparative prose, vanity metrics, section references	clean

Falsified once: one committed frame digest changed. vectors verify, the checker and all three browser engines went red; restored through git, green.

wai-vector: motion/stroke-titles, a title card and a credit roll at 1280x720 and 25 fps ... 2b2fcb5db5

A lower third (a bar and two lines that slide in on an easing table, hold
and fade out as one group), then a heading and five credits, each a role and
the part of the system that filled it, rising three design pixels a frame and
fading out: seven seconds in the default stroke set. Each line's window is
cut to the frames at which every run of it meets the canvas (graphics-vector
section 5.4, Where a block is), computed from the set's exact glyph boxes and
the sink's own track evaluation. The words are written in vectors/text.rs and
name no person, company, product or place.
