/* c3po web UI -- "control deck": a dark blueprint with a crimson accent.
 *
 * The rules the whole sheet obeys, so a later edit doesn't quietly drift:
 *
 *   1. Flat. No box-shadows on content, no frosted glass. Depth comes from a
 *      1px border and a one-step background change, nothing else. The
 *      exceptions: the command palette and the modal, which float over the
 *      page, and the one soft accent glow on "where you are" (the active
 *      sidebar link and the brand dot), as in the mockups.
 *   2. Every border is 1px of --border (semi-transparent indigo). Anything that
 *      wants emphasis uses --border-strong, never a thicker rule.
 *   3. The crimson gradient is an *accent*, not a surface: primary buttons,
 *      active indicators, progress fills, avatars, loading states. Never a
 *      page or panel background. Where a gradient cannot go -- link colour, a
 *      <mark>, a highlighted value -- the flat --accent stands in for it, and
 *      the two must read as the same colour. They did not, once: see the note
 *      on --grad below, which is the mistake this rule now exists to prevent.
 *   4. Two typefaces with a hard split. Sans (--sans) for prose a human reads
 *      in quantity: chat turns, summaries, descriptions, hints. Mono (--mono)
 *      for everything machine-shaped: paths, timestamps, scores, counts, tags,
 *      code, status. The split is the main reason the dense screens stay
 *      readable, so resist "just this once" exceptions.
 *   5. No webfont is fetched. The stacks below name Inter/JetBrains Mono first
 *      and fall through to system faces, because this UI has to work with the
 *      network down (ISSUES.md, "cannot search ... without internet").

  /* accent -- C-3PO brass-gold, flat and in the gradient alike (was polaris's crimson).

     THE LESSON, because it cost two rounds: --accent is the smaller half of
     what anyone sees. A dozen rules paint with --grad -- the brand, primary
     buttons, progress fills, the user avatar, selected-row rails -- and once
     --grad ran violet -> pink -> red while --accent was changed alone, which
     turned the links one colour and left the page another. A gradient stop
     is a colour decision with more surface area than the token named
     "accent", so the two move together or not at all.

     The ramp is a narrow crimson -> rose, so it reads as the flat accent at
     button size. --accent-2/-3 are the mockup's secondary series colours
     (GPU, VRAM, temperature lines), never used for state. */
