//! Compiler **chrome**: the player-visible strings the compiler writes itself,
//! which no campaign authored and no translator was ever asked for
//! (spec-0029 addendum).
//!
//! A delve's on-screen text has two authors. The campaign writes its own lines,
//! and those travel through the l10n inventory ([`crate::l10n`]) into a sidecar a
//! translator fills in. The **compiler** writes the rest — `New objective: `,
//! `Delve Complete`, `Choose your class`, and the default a `bonfire` shows when
//! the campaign authors no label — and without a module like this one they have
//! no key, no sidecar entry and no way to be anything but English, so a player
//! reading a fully translated delve still sees English chrome wrapped around it.
//!
//! ## Why chrome is compiler-owned rather than authored
//!
//! The obvious fix — inventory them like any other string — charges every campaign
//! for text it did not write: a translator answering the same thirteen keys,
//! identically, once per delve, forever. And it would be answering them for
//! **product chrome**: `New objective: `, `Delve Complete`, `Choose your class`
//! are not lines any campaign author wants to write. That eight of them never grew
//! an authored override was a correct judgment, not an oversight, which is exactly
//! why the answer is not to add one — it would move the engine's maintenance cost
//! onto content.
//!
//! The other five are **diegetic**: in-world text a campaign legitimately wants in
//! its own voice, and each already has its authored override (`boundary.message`,
//! `close-gate.sealed_hint`, a bonfire's `prompt`/`rest_label`/`save_label`). Those
//! overrides are unchanged and still win; what lives here is only the **default**
//! the compiler bakes when the campaign authors nothing, which used to be English
//! in every language.
//!
//! ## Key space
//!
//! Chrome keys are `delvewright.ui.<area>.<name>`. The prefix makes collision
//! impossible in both directions, by construction rather than by policing:
//!
//! * a **campaign** key is always one of the fixed kinds the l10n key scheme
//!   derives (`world.` / `area.` / `class.` / `npc.` / `quest.` / `obj.` / `dlg.` /
//!   `wave.` / `actor.` / `loot.` / `cast.` / `fx.`), so no campaign string can
//!   produce a `delvewright.` key — and a sidecar that writes one anyway is
//!   `DW0186` ([`validate_chrome_namespace`]), the guard that sits beside the other
//!   reserved-channel guards;
//! * **vanilla** owns every other namespace in a language file and will never
//!   define `delvewright.*`, so our entries cannot shadow a Minecraft string.
//!
//! ## Sentences, not fragments
//!
//! Four chrome strings frame a value — an objective title, the delve's name, the
//! live party count. They are **one key with `%s` placeholders**, never a key
//! concatenated with a component, because a concatenation freezes English word
//! order into every language: `"%s — complete."` lets a translator put the title
//! where the sentence needs it. Vanilla's `translate` component takes `with`
//! arguments for exactly this, so the placeholder is the intended primitive rather
//! than a workaround (CLAUDE.md no-hack doctrine). A [`ChromeString`] declares how
//! many arguments it takes, and a language table whose placeholder count disagrees
//! with the English fails a unit test rather than a player's screen.
//!
//! ## Delivery, and the honest fallback
//!
//! Chrome rides the same road the campaign's strings do (spec-0029): each chrome
//! string enters emission as a translation tag ([`ChromeString::tagged`]), an
//! emitter lowers it into `{"translate": key, "fallback": <text>, "with": […]}`,
//! and `delvec build` writes the chrome entries into the resource pack's language
//! files beside the campaign's.
//!
//! Chrome is **carried for every language it has a table for and emitted only into
//! the language files the delve already writes** — `en_us` plus the campaign's
//! declared languages. Emitting every table would give, say, a French client on a
//! Chinese-only campaign French chrome around English story: partial in a way that
//! reads as broken, where uniform English does not. The tables still pay off with
//! no engine change: they activate the moment a campaign declares that language.
//!
//! For a language with no table the key is simply **absent** from that file: the
//! client resolves it through `en_us.json` (or, for a player who declined the pack,
//! through the component's own `fallback`) and reads English. Absent, never faked —
//! writing English into `fr_fr.json` would render the same glyphs while claiming to
//! be a translation.
//!
//! ## Translation provenance
//!
//! English is canonical (CLAUDE.md language policy); every table below is derived
//! from it. **These are unreviewed translations** — machine-produced, not
//! checked by a native speaker — which is defensible for thirteen short functional
//! strings and is recorded here so nobody mistakes them for reviewed work. A
//! correction is a one-line edit to a table.
