/*
 * Chirpr: a 2007 Web 2.0 micro-blog for two budgies.
 *
 * Tokens:  sky #bfe8fb · budgie green #5cbf2a · mango #ffd23a · cere blue #2f6fd6 (links) · ink #24323d ·
 *          cards #ffffff on #eef8fd
 * Type:    Lucida Grande / Helvetica Neue (the 2007 Mac web), one family; weight and size do the work.
 * Layout:  wordmark with reflection → the perch (full width) → teach box → feed + sidebar → facts.
 * Rule:    the perch is the one loud thing. Everything else is quiet white cards. Motion only when a budgie posts.
 * Web-safe fonts only (the CSP allows no outside fonts).
