/* Passalong identity (signature pass, 2026-10-06): the list's own subject-line grammar, made calm.
   Ethos: the parents list, only searchable, and gentle. Signature device: the FF / FS / ISO token whose state
   changes live (Pending, Found a home). Mark: the curb sign you stake out for porch pickup.
   Type: Lexend (made for reading fluency) for subjects, tokens and headings; Atkinson Hyperlegible (Braille
   Institute, built for low vision) for everything you read. Both self-hosted, OFL (fonts/LICENSE.txt).
   Colour: warm off-white and sage, pastel tokens with deep same-family text, no black. Spacing 4/8/12/16/24.
   Contrast computed: every text pair AA or better in both modes; control borders 3:1 or better. */
