Drive the existing candidate HWND through CandidatePresenter and msimeui,
keep WebView2 for the menu, floating toolbar, and settings, and load
external skins from skin.toml color tokens. Restore cloud/AI badges on
D2D items, and keep click, pin, fix-position, and delete on the same
window messages as before.
Keep the transparent candidate HWND at wrap-cap width so right-edge
growth adjusts MarginLeft/Top instead of SetWindowPos-moving the host,
which was flashing through layered transparency. Measure/layout keep
horizontal candidates on one row and wrap only inside long items.
Force wrap-aware measure, serialize FineTune after measure content
updates, and preserve flip-up host height via MarginTop.
feat: lazily load single-letter Pinyin candidates
- query the top 24 single-letter candidates from the database
- load the complete candidate list on the first page-down action
- apply the same behavior to Shuangpin and Quanpin
- resolve Shuangpin initials according to the active profile
- preserve candidate frequency adjustment and pinning
- disable deletion for single-letter candidates
- add regression tests for Shuangpin v-to-zh mapping and lazy expansion
Keep horizontal candidates on one line with max-content/nowrap, and resize the host/WebView before painting so content is never laid out in a still-narrow viewport.
