   components.css — reusable UI pieces (buttons, fields, chips, the page
   sheet, nav items). Contract rule 8: every class used anywhere in js/pages/
   must have an entry in the CLASS INVENTORY below, added in the same commit
   that introduces it — this is what keeps this file from drifting out of
   sync with the markup the way an unaudited stylesheet eventually does.

/* The modal. index.html scaffolds the markup and app.js's openModal()/
   closeModal() toggle [hidden] and fill the content, but this presentation
   layer never existed until a real click (not just checking hidden===false
   afterward) proved it: the panel was rendering as a normal block element
   in document flow, ~1700px below the page, instead of a centered overlay.
   Every App.openModal() caller in this app — the year switcher, the mood
   picker, editing a reading-log entry — silently inherited this the whole
   time it was missing.
   [hidden] needs its own rule here: an author stylesheet's plain class
   selector at EQUAL specificity to the browser's built-in `[hidden]{
   display:none}` rule beats it (author styles win ties against user-agent
   defaults), so .modal-root{display:flex} alone would make the panel
   permanently visible — this higher-specificity override is what lets
   closeModal()'s hidden=true actually hide it again. */
