Picking a Home example-prompt card (or "Replicate this content" in the
plugin detail modal) seeds the composer with the plugin manifest's
`description`. Many descriptions were authored with cosmetic hard wraps
(a single newline mid-paragraph, ~75 cols, as if formatted for a
terminal/markdown source). The composer renders the seed with
`white-space: pre-wrap`, so those newlines survived as short ragged
lines that never filled the editor width — leaving a large blank gutter
on the right of the input box (e.g. the Trading Analysis Dashboard
template: 4 hard breaks, ~200px / 29% of the editor blank).
Reflow the offending `description` / `description_i18n` strings in the
56 affected bundled manifests into flowing text (wrapped lines joined,
real blank-line paragraph breaks preserved; CJK joins carry no space).
Surgical string edits only — manifest formatting/key order untouched
(146 lines changed across 56 files). The full build spec still reaches
the agent as plugin context (SKILL.md + example.html); only the
human-facing seed copy changed.
Add an e2e guard (plugin-description-hardwrap.test.ts) that fails if any
bundled manifest description carries an intra-paragraph hard wrap, so
the cleanup can't silently regress when new examples are added.
