Purpose

Prevent awkward line breaks inside single‑word CamelCase company/brand names in Markdown by inserting a zero‑width joiner (ZWJ, HTML entity ‍). This keeps the visual brand token intact across wraps without introducing visible characters.

The rule

Insert a single ZWJ at the primary internal case change of single‑word CamelCase names.
Use the HTML entity form ‍ in Markdown source.
Do not change casing, spacing, or punctuation.

Canonical examples (use exactly as shown):

Hub‍Spot
Linked‍In
Rapid‍SOS
Eisner‍Amper
Frank‍Crum
Hi‍Hello
i‍Capture
Snap‍Addy

Scope and exclusions

Apply ZWJ only to visible text. Never insert ZWJ in:

URLs, email addresses, file paths, code blocks, inline code, IDs, or form inputs
Image alt attributes that must match file names or IDs
Multi‑word brand names separated by spaces or hyphens (no ZWJ needed)
Ordinary capitalized words without internal case change (e.g., “Salesforce”)

How to apply by context

Headings (H1–H6): Apply ZWJ in the visible brand token.
Body copy: Apply on first and subsequent mentions for consistency.
Link text: Apply in the visible anchor text; never modify the URL.
Tables: Apply inside cell text; keep header and body cells consistent.

Context	Apply ZWJ?	Notes
Headings	Yes	Preserve branding in prominent text.
Body copy	Yes	Use consistently throughout the article.
Link text	Yes	ZWJ in anchor text only; URL remains untouched.
URLs/code	No	Never alter URLs, code, IDs, or email addresses.
Tables	Yes	Apply in both headers and cells for uniformity.

Do and Don’t

Do: Insert exactly one ‍ at the main internal case change (e.g., Hub‍Spot).
Do: Keep the entity invisible; avoid adding spaces around it.
Don’t: Add ZWJ to non‑CamelCase words or multi‑word names (e.g., “Bank of America”).
Don’t: Insert ZWJ inside URLs, code, or data fields.

Implementation tips

Authoring: Type “‍” directly in Markdown where the split occurs (e.g., “Hub‍Spot”).
Consistency: If a page contains mixed usage, normalize all instances to the ZWJ form.
QA: Search for single‑word tokens matching CamelCase patterns (e.g., /[A-Z][a-z]+[A-Z][A-Za-z]+/) and confirm ZWJ insertion in visible text only.
Accessibility: ZWJ is non‑printing and should not affect screen readers; verify with standard readers in regression checks.
