+## What 15a, 15b and 15c actually shipped
+
+Read `.agents/context/content-i18n.md` first — it is the language contract and
+it is binding on this task.
+
+- **`src/components/islands/GuideSelector.astro`** — one island, all nine
+ groups. Render it as
+ ``. `data` needs
+ `phases`, `workers`, `trees`, `routes`, `providers`, `efforts`, `skillFiles`,
+ `skillWorkflow`, `commonSkills` and a bilingual `labels` object; the
+ `GuideSelectorData` interface at the top of the file is the exact shape. You
+ server-render each group's shell and its initial detail panel, keeping today's
+ `data-*` hooks and `.active` state. Mark each group `role="tablist"` and its
+ controls `role="tab"` or the keyboard handler will not bind.
+- **`src/components/islands/LanguageToggle.astro`** — render each localized
+ fragment twice, with `data-language-content="en"` or `"pt"` on the outer
+ element. The toggle flips `hidden` on those, sets ``, and fires
+ `ai-for-dummies:languagechange` on `window`. It is a plain `.astro` island
+ that defers its own setup with `requestIdleCallback`; **do not** put
+ `client:idle` on it — that directive is framework-components only.
+- **`src/components/islands/CopyPrompt.astro`** — one per button. Pass
+ `target="prompt-install-skills" | "prompt-basic" | "prompt-skills"`. Render
+ `` exactly once on the
+ page; the island writes into it. Fill the `
` bodies
+ from the `handsOnPrompts` and `skillInstallPrompts` collections — 15b verified
+ those are byte-identical to the legacy `app.js` constants, and the clipboard
+ copies whatever you render, so do not reformat them.
+- **`src/components/islands/ReadingProgress.astro`** — replaces the legacy
+ `` at the top of the page.
+
+Nothing else is missing. If you are about to write an island, you are doing
+another task's work — report the gap instead.
+
+## Two things to expect
+
+- **The snapshot will not match by construction.** Dual-locale rendering emits
+ both languages into the HTML where today's page emits English plus a
+ Portuguese map inside `app.js`. Compare _rendered, language-filtered_ output
+ against today's page, and if `.agents/snapshots/` needs regenerating, say so
+ explicitly in your report with what changed and why — do not quietly rewrite a
+ snapshot to make a diff go away.
+- **`renderHandsOn` takes no argument** and is not part of GuideSelector's
+ nine-group pattern. It is yours. Its name is asserted by `verify.mjs`.
