274: two named parking bays; roster trimmed to 132

50.52  紅葉山駐車帯  41 m off  夕張市紅葉山
57.08  楓駐車帯     39 m off  夕張市楓

Both signposted and both absent from OpenStreetMap, which carries no
parking or rest-area features anywhere on this stretch. One of them is a
bay the author had previously recorded as unnamed. Responsible body is
北海道開発局 札幌開発建設部 岩見沢道路事務所 by jurisdiction — R274 is
指定区間 全線 and every adjacent structure registers to that office — but
no document names either bay, since parking has no published register.

Author's trimming removed 38 rows: the 丁目 grid, all five bus stops,
川端駅, and some civic furniture. That leaves 132 rows with 132 distinct
object names, so the planned lyric-to-row index is unambiguous with no
special case except モトツ橋/シェルター, which already share coordinates.

274-romaji.py learns ちゅうしゃたい and ていしゃたい so parking bays split
as Momijiyama chuushatai rather than one run-on token; --check is clean.

CSV and GeoJSON re-propagated from the Markdown.
