/* === Mobile hardening (Terminal theme) ==================================
   The Terminal sheet is a full swap, so the field-manual mobile hardening in
   cards.css (its .body overflow-wrap + pre max-width block) does NOT apply when
   this sheet is active. Without it, long unbroken literals (64-char SHA-256
   hashes, UPPER_SNAKE receipt tokens like W6_KANSA_BLOCK_BUSINESS_RULES_FAILED,
   and command strings) and wide code/receipt blocks pushed the whole card past a
   390px viewport in Terminal while the field-manual theme stayed bounded. This is
   the same additive fix, mirrored here: overflow-wrap is inherited from .body so
   it reaches inline <code>, <strong>, and .dod-text; <pre> and .prompt code keep
   their own white-space (pre / pre-wrap), which wins over overflow-wrap, so
   formatted command blocks stay intact and scroll via their existing overflow-x;
   min-width:0 lets those boxes shrink inside flex parents. All additive: on
   desktop nothing is long enough to trigger a break, so layout is unchanged. */
.body { overflow-wrap: anywhere; }
/* ...except inside tables, where `anywhere` shatters ordinary words when the
   browser computes a column's min-content width. `break-word` still wraps a
   genuinely oversized literal but sizes columns off whole words again. */
.body th, .body td { overflow-wrap: break-word; }
.dod-text { min-width: 0; }
pre { max-width: 100%; min-width: 0; }
@media (max-width: 640px) {
  .body table { display: block; overflow-x: auto; }
}

/* === Hero-glow page-overflow fix (independent 390px browser QA) ==========
   The block above keeps command/receipt <pre> and long literals scrolling
   inside their own box, but it is NOT what pushed the whole page sideways at
   390px in the Terminal theme. The remaining page-level horizontal overflow is
   the decorative .hero-glow: a 600px circle anchored at left:-180px, so its box
   spans x=-180..420 and its right edge (420px) sits 30px past a 390px viewport,
   which is what drove documentElement/body scrollWidth to ~420px. .hero itself
   dropped overflow:hidden (Option A, see .hero above) so the glow can feather at
   the top edge on desktop, so nothing clips the glow horizontally on a phone.
   Clip it to the hero box on narrow viewports only. overflow-x:clip (not hidden)
   removes the glow from scroll width without turning .hero into a scroll
   container, and overflow-y:visible keeps the top-edge feather intact. Desktop
   (>900px) is untouched, so the glow still feathers there. */
@media (max-width: 900px) {
  .hero {
    overflow-x: clip;
    overflow-y: visible;
