+        Brightness decides which pixels are lit, and alpha is deliberately
+        ignored. Every asset on disk is mode "1" carrying a tRNS chunk, and both
+        loaders open them with .convert("RGBA"), which turns the WHITE (lit)
+        pixels into alpha 0 and the black ones into alpha 255 -- exactly
+        inverted. The previous rule, `a > 0 and (r or g or b)`, was therefore
+        false for every pixel: lit ones failed the alpha half, unlit ones failed
+        the colour half. The result was a fully transparent tile, so the clock
+        drew nothing at all.
+
+        Do not "restore" an alpha check here. By the time this runs the alpha is
+        already inverted, so honouring it blanks the display again.

The digit and separator assets are 1-bit bitmaps with a transparency chunk, so loading them with .convert(\"RGBA\") hands back alpha 0 for the lit (white) pixels and alpha 255 for the unlit black ones -- exactly inverted. The recolour step asked for \"visible AND not black\", which was false for every pixel: lit ones failed the visibility half and unlit ones failed the colour half, so each frame came out fully transparent and the panel stayed dark. Lit-ness is now read from brightness, which the inverted alpha cannot affect. All eight safety-harness renders match the goldens captured before the regression, so the display returns to exactly what it drew before rather than merely drawing something.",
