/*
  Wakuya Studio Portal - v1 styling.

  Design tokens below are Yui's real, confirmed values (requirements §7.7
  Decision 1, design/studio-portal-v1-ux.html §00-§01): the portal reuses
  Wakuya's existing dark-ground/copper-accent brand system verbatim - same
  token names and values as design/home-mockup-v7.html and Akane's
  brand-handoff-v8.html, not a separate "internal tool" palette.

  Layout below (2026-10-03 pass) implements her full mockup: left-nav-rail
  app shell (desktop) / hamburger + drawer (mobile, via a checkbox hack -
  no client JS required for the drawer itself), card-based Sprint/Pending
  layouts, a redesigned login screen, and her §08 accessibility checklist
  (skip link, visible focus, prefers-reduced-motion, aria-pressed lang
  toggle - markup for the ARIA/skip-link pieces lives in the view
  templates/partials, this file only carries the corresponding CSS).
*/

/* ---- Self-hosted fonts ----
   4 families copied from the public website's existing self-hosted set
   (website/assets/fonts/, see that file's 2026-09-26 comment for the
   original third-party-request rationale) at the weights currently
   applied below. Noto Sans JP is new for the portal specifically (the
   website correctly dropped it as unused) - content-subsetted rather than
   the full CJK repertoire; see portal/docs/FONTS.md for why and how to
   regenerate it. Linked separately as /css/noto-sans-jp.css (see
   views/partials/head.ejs) rather than @import'ed here - CSS requires
   @import to precede every other rule in the same file, which would force
   reordering this whole file just to accommodate it. */
