Version 0.45.1

Fixed the first line on the home page washing out once the 3D lighting arrived.

The home page draws its opening sentence over a moving 3D stage with a soft dark plate behind the text, and when the stage's 1.4 MB lighting file arrived seconds after the first paint the white shapes went near-white and the plate was no longer enough. Measured on the real page: at 390px wide, 48% of the headline's pixels fell below the 4.5:1 contrast ratio and 10% below 3:1 — the floor the accessibility guideline sets for text that size — and at 1440px it was 61%. The cause was position rather than strength, because the plate was centred on the whole block of copy while the headline sits at that block's top edge where the plate had already faded, so the plate is now larger and centred higher and nothing is below 4.5:1 at 390, 768 or 1440. The stage is as visible as before; a stronger plate in the same place was tried first, painted a visible band across the stage, and was rejected.
