+Add `--pkg-di`, blue `#3E7FD4`, for `@btravstack/di`.
+
+Blue is plumbing — the connections behind the wall that everything visible runs
+on, which is what a wiring container is. The hex is the logo's own lighter blue
+(the barrel rim, the plunger, the needle hub), so chrome and artwork stay one
+color.
+
+di's docs site currently sets `--accent: #2A62B8`, the logo's *deep* blue. That
+hex scores 3.22 against `--card` on the dark scheme, below the 5.00–7.25 band
+the other four package accents occupy, so the landing takes the lighter blue
+instead: 4.72 on the dark card, 7.10 as darkened text on white (AA). Repointing
+di's docs to match is btravstack/di's half.

 **The idea.** Studied from the user's stated inspiration. The org is a
 *colorful stack of distinct tools* on a near-neutral black canvas: the
 beetroot pink is the ORG accent (wordmark, links, CTAs, mascot), while each
 package glows in **its own accent** — amqp orange, temporal indigo, unthrown
-teal, entity amber. Weight-contrast typography (one grotesque at 400 vs
-800), elevation through surface lightness, real numbers in the hero, and the
-gradient beetroot mascot as the one character moment.
