   Scoped entirely under .tsl-doc so nothing here can leak into the global
   .legal-page rules still used by legal_notice.html and dpa.html.

   Read mode: the visitor has to UNDERSTAND this document, so the whole layout
   is built around comprehension of a long reference text - a persistent table
   of contents, citable numbered sections, a 68ch measure, and real tables
   instead of prose for anything the reader will scan rather than read.

   Tokens are the shipped TitanShield dark theme (DESIGN.md): board-case
   #101216, board-face #1a1d22, hairline #2c3138, flap-ink #eef1ee,
   flap-ink-dim #8f99a3, text-tertiary #6b6966, resolved #00d972.
   Rectilinear, 2px radius, hairlines only, zero shadow, zero gradient.

   Reclaiming the global theme
   -----------------------------------------------------------------------------
   Three app-wide rules would otherwise land on this document and each one is
   wrong here:
     1. animations.css sets `h1 { background: var(--gradient-primary);
        -webkit-text-fill-color: transparent }`, so every H1 renders as gradient
        text. DESIGN.md bans gradient text: emphasis comes from weight and size.
     2. v4-theme.css sets `h1..h6 { font-family: var(--font-display) }` where
        --font-display is Outfit, not the Titillium Web this project's design
        system actually specifies.
     3. v4-theme.css sets `[data-theme="dark"] a:not(...)` to #00d972, an
        attribute+element selector that outranks a single class, which turned
        every table-of-contents entry and every body link into the same loud
        green. The accent belongs on real links, at the accent value #00d972,
        not on navigation text.
   Scoped under .tsl-doc, so no other page is affected.
