## Generated placeholders

No suitably-licensed Commons photo could be found for these slots after a
genuine search (5+ queries each, in English and Japanese, across several
search rounds — e.g. "roof drain debris", "ルーフドレン", "silicone caulk
window frame", "コーキング 劣化", "タイル 浮き 外壁", "ベランダ 床 防水",
"配管貫通部 シーリング", etc.). These are generated placeholder JPEGs: a
soft grey-blue gradient (#e3e8ef → #cbd5e1) with a centered Japanese
caption naming the subject, rendered with Hiragino Sans. They are not
photographs and carry no license/attribution requirement — they exist
purely as visual stand-ins for the mockup layout.

| File | Placeholder caption |

| `roof-topcoat.jpg` | 写真：トップコート劣化 |
| `roof-blister.jpg` | 写真：防水層の膨れ |

## Reproducing this set

Run `python3 scripts/fetch-photos.py` from the repo root. It re-downloads
each real photo from Commons (via the API, no key needed), re-applies the
same center-crop/resize/strip-EXIF/JPEG-quality-82 processing, and
regenerates the placeholder images. The exact Commons file titles chosen
for each slot are recorded in that script.
