/* =====================================================================
   网盘 — 面板样式表
   =====================================================================
   Built on 3x-ui's design language rather than its surface. The parts
   that were actually copied, and why:

   1. The page is NOT white. A tinted page (#e6e8ec / #1a1b1f / #000)
      with white-ish cards floating on it is what makes a panel read as a
      panel. Cards on a white page look like nothing.
   2. Three themes, not two: light / dark / ultra (true black). 3x-ui
      ships an explicit toggle instead of only following the OS, so the
      brand row carries one and the choice is persisted.
   3. Every page is the same three beats: summary strip → action card →
      data card. Nothing floats loose on the background.
   4. Inside a card, grouping is done with 1px rules between cells, never
      with nested boxes.
   5. A strict type ladder does the hierarchy work:
        kicker  11px UPPERCASE .08em  — the label above any value
        sub     10px UPPERCASE .06em  — the label inside a split cell
        value   19px/600               — a normal figure
        hero    34px/600 -.02em        — the one big figure on a card
      and every numeral is tabular-nums so columns of figures line up.
   6. One accent, plus threshold colouring shared by rings, values and
      the health line: <80% accent, 80–90% amber, ≥90% red.
