Every reference to the Driver in library/ is reworded: the engineering reason stays, the speaker and the quote go, and a decision still open reads "provisional, pending a product decision". Comments only: each changed file is identical after stripping comments (JavaScript, template and CSS, including CSS comments inside the style strings shadow-DOM components inject). Those style-string comments do ship, so several bundles change by exactly those comment bytes.

/**
|
||
* build-points.mjs — the COMPACT point file All People Groups renders from.
|
||
*
|
||
* node library/scripts/people-groups/build-points.mjs
|
||
* reads data/people-groups/people-groups-slim.json (12,379 rows × 22 keys, ~7.5 MB)
|
||
* writes data/people-groups/people-groups-points.json (only the 10 fields the map uses)
|
||
*
|
||
* WHY. The map downloaded and parsed the whole slim file — every column, as one object per row — to
|
||
* draw ten fields. That, plus waiting on the live prayer API before drawing anything, is most of why
|
||
* the map seemed not to load at all, or took a very long time. This file keeps the same rows and
|
||
* values in column order, with the repetitive strings (country, religion, evangelical level,
|
||
* language) stored once in dictionaries and referenced by index, and coordinates at 3 decimals
|
||
* (~100 m, far below a pin's size at any zoom this map shows).
|
||
*
|
||
* Deterministic: same input, byte-identical output. Re-run after refreshing the slim file.
