/* --- Theme 1: Caves of Steel (Earth) ---
   The enclosed City: eight million people under one roof, no sky, permanent
   artificial light. Two book details drive the palette away from generic dark
   mode: the accent is low-pressure *sodium* amber (#FFB000) — the real colour
   of the lighting a domed City and its expressway strips would run on, where
   the old #FFC700 was a lemon yellow no sodium lamp emits — and "positive" is
   yeast-vat green, since Earth eats what the New Jersey yeast farms grow, not
   the neon #00FF66 of a terminal. Greys carry a faint blue-steel cast: steel
   and concrete, not warm carbon. Sharpest radii of the four. */

   Twenty thousand people on a whole planet, ten thousand robots each, and a
   sun so exposed it is the thing Baley cannot bear to stand under. The word is
   *bleached*, so every neutral here is cold: the old palette's alabaster beige
   (#F0ECE1 / #E5E0D5) was the single biggest reason this theme read as a
   slightly duller Dawn instead of its opposite, and it is now cold grey. The
   accent is Solarian estate cypress pushed toward teal — the only saturated
   thing on an over-lit world. Slowest transitions of the four (Solarians do
   not hurry, and they meet by "viewing", never in person). */

   wrong depth: #8C4303 reads brown, not sunrise, and left no headroom. The
   accent is now a deeper terracotta struck by low sun, the category ramp gains
   the violet of the sky before sunrise (funding) and a true rose
   (competitive), and the neutrals stay unapologetically warm — this is the one
   theme allowed to be, since it is what Naked Sun is now defined against. */

/* --- Theme 4: Robot Dreams (the subconscious) ---
   Repainted off cyan-on-midnight, which owed more to stock sci-fi than to the
   1986 story. What Elvex actually dreams is a colourless grey in which robots
   labour, lit by one distant sun — so: a grey-indigo ground (not a saturated
   space blue), warm-silver text, warm-grey hairlines, and a single amber light
   as the accent. The glass surfaces and the glow stay, because the dream is
   still soft-edged and lit from within; only the hue moved. `--accent-on` is
   still mandatory inside any accent fill — amber on warm silver is ~1.9:1. */

/* Priority+ nav. Every section link ships once, in .nav-list; app.js moves the

   CSS has to hold up:
     - the nav must be the flex item that absorbs the leftover width, so
       `nav.clientWidth` is the space JS is actually fitting into — hence
       flex:1 1 auto + min-width:0 rather than the old margin-left:auto only;
     - before JS runs (and with JS off) nothing may be unreachable, so the
       default is a horizontally scrollable chip strip. .nav-managed, added by
       app.js, hands overflow back to the dropdown. */

     moved out and the siblings relaxed back to their natural widths. The
     layout was fitting to a width that no longer existed by the time it
     finished, which is what printed "US vs China" underneath "Sections".
