Issue Resolved / Feature Added

NXT-15426 — Refactor Limestone screenshot test scenarios into a maintainable, smoke-oriented structure and reduce redundant derived cases (focus, RTL, large text) without dropping QWTC coverage.

The full screenshot suite had grown large and repetitive: the same configurations were copied across LTR, focus, RTL, and locale blocks. This PR reorganizes scenarios per component, uses shared helpers, and trims duplicate definitions while keeping one representative case per visually distinct configuration.

Resolution

1. Structural refactor — 55 files under tests/screenshot/apps/components/:

Group scenarios into named arrays (e.g. buttonSmokeTests, buttonCommentedTests, buttonQwtcTests, focus/RTL/locale variants).
Shared helpers in utils.js: withConfig, withProps, pick, LoremString, LongerLoremString.
QWTC-documented cases kept with Jira annotations.
Lower-priority permutations moved into *CommentedTests where appropriate (still exported where not yet trimmed).

2. Smoke deduplication — net ~−1,700 lines vs develop:

pick(tests, …indices) selects smoke representatives for RTL, large text, and similar derived suites.
Focus tests keep distinct scenario titles (e.g. Focused Update, Hello Focused CheckboxItem) — same convention as develop. Screenshot titles are derived from props/children only; focus: true is not part of the title, so reusing smoke JSX under withConfig({focus: true}) would compare against the wrong Nebula reference when REFERENCE=develop.
Fixed focus/QWTC alignment in CheckboxItem, Chip, Chips, ProgressButton, SwitchItem (QWTC cases back inside withConfig({focus: true}, …)).

3. PageViews fix — correct RTL scenario selection (pick from commented scenarios where smoke indices were wrong).

Example (Chip.js): smoke list defines visual variants once; focus uses a small dedicated list (Focused Default Chip, …); large text uses pick() from smoke where titles remain unique per skin variant.
