# Good things have roots.

Independent article case study. Domain: website consumer / Design Engineering presentation.

A native range and pointer position share a clipping value for an original SVG pot cross-section. Stable feature selection drives reusable callouts. The care button has idle, hover/focus and expanded states, while its semantic expansion state commits immediately.

Studied: [From Static to Dynamic: 3 Micro-Animations Every Web Developer Can Master with Rive](https://tympanus.net/codrops/2025/07/01/from-static-to-dynamic-3-micro-animations-every-web-developer-can-master-with-rive/), Jeff McAvoy. Article SHA-256: 4e606fd30b5b746c5937bd34f1900321af6aae5794c6fc2ca053987c63551302. Analysis SHA-256: 2daef579d5e01881dfca234d7b26ea425af51e442498434b2451ca9f14a71e97. Source revision: e3adbb7bfdf553a5ed5c30de8f17f7b3a03dcf0469972d1e509a0ae5dbb7a681. The revision hashes the article/analysis hashes, the analyst principle and code-block evidence references; it identifies studied evidence, not a claim that the original demo executes.

Original acquisition: unresolved. Original license: unverified. originalSourceAcquired: false. The public article and Rive community link are present, but no original licensed .riv file/export was acquired. Two starter-button fragments do not constitute the three animated patterns.

No original article prose, code, artwork, source project or screenshot is distributed here. The authored-code MIT notice applies only to the independent implementation. The two button snippets do not constitute the complete three-pattern implementation. Do not present the original TapRoot artwork or Rive state machine as recovered.

## Initial state and controls

An original plant illustration opens a view below the soil. Reveal the root layer, choose a feature, and open the care plan through a native button.

The page starts stationary. Play motion, where present, advances this study’s presentation until paused; text, bounce, portrait, orbit, strand and mascot motion loops, while the event composer stops at its endpoint. Scroll studies advance through ordinary document scroll or their chapter buttons. Static view stops time-based motion; manual controls still inspect values. The three scroll studies instead show every chapter in ordinary reading flow. Pointer parallax centers its decorative layers.

Initial control values:

| Control key | Value |
| --- | --- |
| reveal | 58 |
| width | 100 |

## Running and editing

Open index.html directly. It contains all runtime code and visuals and needs no package install, account, network, remote asset or browser-origin storage. Edit its inline style and script to change the downloaded page. styles.css and script.js are reference copies of the inline source; changing those copies alone does not change the running page. Repository regeneration overwrites index.html and all generated copies, including any manual edits. Keep a separate copy when editing a download. The repository authoring modules in vendor/codrops-article-studies/scenes-*.mjs and runtime.mjs regenerate these copies through node scripts/build-codrops-article-studies.mjs. Repository regeneration also needs the private source evidence; downloaded-page execution does not.

## Verification boundary

This generation passed the captured article/analysis hash checks, exact ID membership, local canonical Markdown anchor/hash checks, implementation-symbol checks, JavaScript parsing, semantic main/title counts, duplicate-ID checks and runtime URL/storage exclusion. The manifest codeFiles entries identify every emitted file by SHA-256. Each code symbol is a searchable named function, not a claimed executed call trace. Proposed checks are in KNOWLEDGE.json. runtime_verified: false. SG artifact capture proves only a recorded initial render; no interactive runtime, keyboard, accessibility, comfort or performance result is claimed.

Manual Chrome interaction is blocked by extension UI in this session. No alternate browser-control route was used. Preview sizing is native responsive width. Initial-render captures are tracked separately at site/artifacts/full-import/preview-posters/index.json and site/artifacts/full-import/preview-posters/visual-review.json in the repository. No capture receipt is bundled with this download. The bounded initial-render matrix requests all 21 studies at 320 pixels and three representative studies at 1280 pixels; the separate poster surface is 640 × 420. The authored CSS also adapts at 375 and 768 pixels, without claiming those widths were captured. A width request does not mean that capture exists or passed. Motion starts on explicit playback; system reduced motion and the Static view switch stop it.
