Subject: [PATCH] =?UTF-8?q?fix:=20malformed=20supporter=20SVGs=20=E2=80=94?=
 =?UTF-8?q?=20Boeing/Ribose=20invisible,=20NIST=20oversized?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

boeing/ribose shipped viewBox-only SVGs (no intrinsic width/height), so
the logos collapsed to nothing under w-auto + height caps; nist shipped
width/height without a viewBox, so its content could not scale and
rendered oversized (ge had the same latent problem). Give all four both
a viewBox and explicit dimensions, and set a definite h-10 on the logo
strips so every logo renders at the same height.

scripts/assets.test.ts guards the invariant: every supporter SVG must
carry a viewBox and explicit width/height.
