Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🔵 Low · up to Story controls can change displayed formatting without updating the related search filter, which may make the Username examples behave inconsistently or mislead users of the documentation.

- Around line 254-258: Update the Username story filtering flow to extract
isCompact, fullNameFormat, and formatter before filtering, then build the filter
text from the same primary, secondary, and site values rendered by the story
instead of hard-coding formatUsername(user, 'lf.m.'). Keep filtering and
rendering aligned when story controls change.

Может, query?: string | string[] — подсвечивать несколько слов сразу?

Не совсем понимаю зачем это и как должно работать в случае пересечений.
Пока сделано так же как в angular.

Вместо offset можно взять index из map.
{parts.map((part, index) =>
part.isMatch ? (
<mark key={index} className={s.mark}>
{part.text}

) : (
part.text

[Highlight] - ссылка
…s (DS-4815) Applies code-review findings from the Highlight component: query matching now tolerates diacritics to stay consistent with useFilter's locale-aware contains/startsWith, render output is memoized with stable mark keys, and the bold variant sources its weight from a design token instead of a literal. Also fixes the SearchAndHighlight story's hand-rolled Primary/Secondary/hint composition, which had silently diverged from Username's own isCompact, fullNameFormat, and hint-placement behavior.
…(DS-4815) Adds the missing displayName on the polymorphic Highlight component, matching Typography and Container, and regenerates the Username API Extractor report for the newly exported usernameHintAffixes. Splits the react type imports back onto their own line (as in ButtonGroup) so the generated Highlight report keeps its `import type` form.
The SearchAndHighlight story filtered with a hard-coded formatUsername(user, 'lf.m.') while rendering with the formatter and fullNameFormat from args, so changing either control searched different text than it displayed. Compact mode had the same gap: the login was hidden but still matched. Derives the primary, secondary, and site values once and uses them for both filtering and rendering, so the two cannot drift apart.
