/*
 * data-test="W-126-1-overlay"
 * Wave-126 — bundled-POST upload overlay. Per spec/80 §"Wave 126" the
 * overlay sits on top of the screen stack while the W-125-2 bundled
 * captures POST is in flight. Copy is "Almost done..." — chosen
 * because the Q11-verbal stem (see CLAUDE.md Rule-5 forbidden list)
 * is not permitted in the (go) tree. All colour values reuse the
 * :root tokens defined at the top of this file so the wave commit
 * passes CLAUDE.md Rule-3 (no new hex/rgba added).
 *
 * Spinner uses conic-gradient + transform: rotate (lesson H5 — prefer
 * transform over top/left to avoid layout thrash on low-end Android).
