/*
  BACKTRACE: tactical debrief aesthetic
  ---------------------------------------
  Dark-only by design (this product has one identity, not a light/dark toggle).
  Cold charcoal base, phosphor-cyan accent, real CS2 side colors (CT blue / T tan)
  for team identity, and a reserved good-to-critical status scale for grades.

  Structure comes from rule weight, not boxes: a heavy rule opens a data block,
  a hairline closes it, dense tables get thin row dividers. There are no card
  containers (border + background + radius) anywhere in this file on purpose -
  team identity is a colored rule under the roster name, not a dot; the upload
  target is a corner-bracket reticle, not a dashed box.

  Type is two-tier: Rajdhani (squared, technical, close in spirit to Valve's
  own Stratum2, which is not something this project can legally embed) carries
  headlines and titles; Noto Sans carries body prose. Both are self-hosted
  locally (fonts/, SIL OFL licensed), so there is no runtime CDN dependency
  and no build step. All numeric data stays in a monospace face with tabular
  figures - the one typographic bet that doesn't move.

  Palette validated with the dataviz skill's validate_palette.js:
  - team-ct/team-t pass the categorical six-check (lightness band, chroma floor,
    CVD separation, contrast) against this file's --bg.
  - accent + status steps checked for WCAG contrast against --bg and --surface.
