- Nodes carrying an infinite CSS animation at ANY viewport get their frozen
mid-animation transform zeroed at EVERY viewport (the @keyframes owns the
property at runtime); animOwnedProps is now viewport-aware so breakpoint-
gated marquees can't bake a mid-scroll translateX into other bands
- contentSizedFlexRow/contentSizedFlexItemAuto honor the sizing probe: a
flex item whose captured width the probe proved load-bearing
(wAuto=false) is never converted to width:auto, preserving narrow
centered text columns
247 tests pass (7 new), typecheck clean.

- heightFlows() bails when the capture probe proved a height authored-
explicit (hAuto=false, hFill=false), so circular parent/child flow
reasoning can no longer drop 100vh heroes to 0px; the probe verdict now
vetoes the drop through both OR'd paths at the call site
- Space-distributing flex columns (space-between/around/evenly, center,
flex-end) disqualify the content-driven read - the box height is load-
bearing for the distribution
- Lottie mounts pin their captured per-viewport height like other replaced
content, so aspect-fit runtime svgs can't inflate past the captured box
- DittoLottie forwards the placeholder's data-cid onto the runtime svg/
canvas so the media stays addressable after the swap
240 tests pass (9 new), typecheck clean.

Capture:
- Preserve real asset extensions (.lottie no longer truncated); extract the
default animation JSON from dotLottie ZIP containers at materialization
(minimal built-in ZIP reader, no new deps)
- Reset scroll + settle before every viewport snapshot so scroll-linked
styles can't bake into captured computed values
- Marquee detection now requires content overflow (>1.35x), sustained
velocity across separated windows, scroll independence (jiggle test), and
genuine content repetition — kills scroll-settle-lerp false positives
- Sizing probe trusts authored explicit heights (px/vh/calc) over circular
parent/child reflow verdicts, fixing dropped 100vh heroes
Normalize/generate:
- Canonicalize identity transforms to "none" per viewport; emit explicit
transform resets across bands when any band has a real transform
- DittoLottie keeps the captured placeholder until DOMLoaded; failed loads
no longer blank the container
- mx-auto only for true auto-margin centering; literal per-band margins are
preserved (fixes full-bleed regressions)
- Spacing-scale snap tightened to 0.25px (3.5px stays p-[3.5px]); emit
whitespace-nowrap for wrap-vulnerable single-line text leaves
- Grid recipes no longer override captured track counts or column spans;
responsive re-flow plans apply only when geometry agrees
Quality scoring:
- Rewritten 6-dimension rubric (payload, decomposition, duplication,
semantics, hygiene, runtime) with catastrophe caps and per-dimension
reporting; thresholds are documented calibration guides
218 tests pass (74 new), typecheck clean.

- DittoWire/Accordion/DropdownMenu runtime templates: AbortController-based
listener cleanup, idempotent effects, orphan panel removal on unmount
- Emit a single src/lib/utils.ts cn() instead of a copy per component file
- Collapse captured whitespace runs under white-space:normal (pre* preserved)
- Tag source-injected font-metric probe nodes at capture; drop them from IR
- Snap sub-pixel arbitrary lengths (integer within 0.1px, else 1 decimal)
- Emit SITE_ORIGIN (src/lib/site.ts, env-overridable): sitemap/robots/
canonical/og:url/JSON-LD resolve against the clone's own origin instead of
the source domain
- Pin lottie-web in generated package.json whenever DittoLottie is emitted
144 tests pass (21 new), typecheck clean.

Three clone-fidelity fixes from manual review of the acceptance screenshots.
Fix 1 — mobile nav chip-strip overlap (generate/css.ts). A horizontally
scrollable flex strip (overflow-x:auto flex <ul>) of nowrap chips collapsed
because the base viewport reported min-width:0px on the chips (a mobile-only
strip that is 0-wide at desktop), so the generator emitted `min-w-0`, letting
the chips shrink below their content instead of overflowing — the nowrap text
then collided. Suppress `min-w-0` for a nowrap flex item whose flex parent
scrolls horizontally; scoped away from legitimate min-w-0 truncation (whose
parent does not scroll-x). Verified on a fresh ooni.com clone: 0 chip overlaps
at 375, scrollWidth 776 > clientWidth 375.
Fix 2 — reveal-replay stagger leaves tiles unpainted (generate/motion.ts).
DittoMotion re-hid each revealed element and replayed its entrance on
scroll-into-view preserving the captured delay/duration, so a fast scroll /
full-page screenshot caught most grid tiles mid-entrance. Cap the replayed
delay (<=300ms) and duration (<=600ms), settle each tile per-element a bounded
time after it enters view, and make the global failsafe settle (not re-animate)
so nothing stays hidden. Validator settle path (__dittoMotionStop) unchanged.
Verified: cropin cotton renders 12/12 crop tiles in a normal full-page pass;
motion gate reveals 24/24.
Fix 3 — scroll-linked text-fill frozen at end state (capture/stabilize.ts,
capture/capture.ts, generate/css.ts). A view-timeline text-fill
(animation-duration resolves to `auto`) was baked filled: the clone has no
scroll timeline, so emitting the animation made it jump to its end keyframe via
fill-mode:both. Capture-side, cancel scroll/view-timeline animations before each
snapshot so the DOM records the at-rest state; generation-side, suppress the
animation-* props when animation-duration is `auto` (we render the at-rest
state, never replay a scroll-linked animation). Teach the motion gate to exclude
these from the static-CSS expectation so the gate stays honest. Verified on a
fresh ooni clone: the "world's no.1 pizza ovens" em is white/gray (rgb 240,240,
240), not filled yellow, at rest; motion gate still passes.
Tests: +7 fixtures (css scroll-strip + scroll-timeline, reveal-replay caps,
motion-gate scroll-timeline exclusion); 123/123 compiler tests green, full test
suite green, typecheck clean. No gate regression on the fresh ooni run vs the
20260704-024247 baseline (all gate pass/fail unchanged; perceptual within
0.0004; motion restored to pass).

Round-3 fixes from gate validation + human visual review of fresh
cropin.com and ooni.com clones:
- app.ts: section data-var rename used an unanchored substring replace,
so Tile2_data matched inside MediaTile2_data and emitted a corrupted
Mediatile2Data usage (ReferenceError at prerender). Word-boundary
regex; every map site now shares one derivation.
- graft.ts: about:blank iframes were blanket-skipped, missing the
Klaviyo newsletter form (mounted into a blank same-origin frame via
JS) — the audit's #1 complaint. Blank frames now graft; the
visibility gate still excludes 0-size tracking pixels.
- walker.ts: isVisible() now rejects boxes wholly outside the viewport
(off-left always; off-right only when the page isn't horizontally
scrollable; fixed boxes fully above/below), so a closed slide-in
drawer's contents no longer count as expected text (91.8% -> 93.4%).
- css.ts: four sizing-regime corrections — pin captured px for
circular shrink-0 slides (Splide slide chain collapsed 0x0);
flex-basis:100% for full-width shrink-0 slides; keep fixed-px grid
templates for scrolling track lists (repeat(N,1fr) squished a
50-track carousel); single full-bleed fixed track -> minmax(0,1fr);
keep authored heights whose in-flow children are fill children
(aspect-video heroes inflated 240 -> 720px); width:100% for
inset-spanned aspect boxes.
Gate scores: ooni home 88.7 -> 93.3 (responsive 32 fails -> pass),
pizza-ovens 90.8 -> 97.6 (perceptual 46.7% -> 17.2%).
107/107 compiler tests, all workspaces green.

Capture (4a):
- stabilize: dwell-scroll settling pass + known-library pre-reveal
neutralization after lazy promotion, so every viewport snapshot records
the post-reveal steady state (about-page sections no longer captured
blanket-hidden: 24 base `invisible` wrappers -> 0)
- probeReveals: extended to the visibility + entrance-animation family;
DittoMotion replays them (JS re-hide on mount, IntersectionObserver
reveal, 4s force-reveal failsafe) so SSR/non-JS still shows content
- assets: 206 range-response bodies are no longer stored as full assets
(full-fetch fallback) + video magic-byte validation - the about-page
hero video is now a valid 6.0MB ftyp mp4 instead of 18.9KB of garbage
Generate (4b):
- css: hidden-node geometry policy - a visibility:hidden box with a 0x0
captured bbox at a band becomes display:none there; an OCCUPYING hidden
box gets the captured per-viewport geometry instead of the baked
canonical one. Also covers the ancestor-hidden-at-base case (the
cropin.com/cotton slider arrow: hide inherited from an elementor-widget
ancestor at every width parked a desktop left:548px box inside a 375px
viewport -> body.scrollWidth 585; now 375 on both verified pages)
- tailwind: bare-zero utility gating - font-size:0 -> text-[0px] and
letter-spacing:0 -> tracking-[0px] (text-0/tracking-0 are silently
invalid in Tailwind v4; fixes permanently-visible map labels on the
cotton Global-presence section)
Verified: 87/87 compiler tests green, full-workspace suite green,
regenerated cropin.com + /cotton/ builds measure 375px scrollWidth at a
375px viewport, and a fresh /about/ clone renders all reveal sections
with scroll-replay against the live site.
