   "request": "Work on the existing kolossal website repo. Start with the Referenzen (case studies) section. Right now it's a staggered two-column arrangement with the left column dropped down as a whole, and by the time you scroll halfway the right column bottoms out first — it looks unfinished, and clients have complained. Please turn it into a proper three-column grid: all cards top-aligned and the same height (use 480px), keep the current 30px gaps between columns and rows, and leave the card corner radius alone at the big 40px. None of the six cases' existing titles, German descriptions or \"Case ansehen / Website ansehen\" link copy may be lost. Also, we'll have more cases over time, so add a toolbar at the very top of this section; when scrolled past the case area it should stick to the top of the viewport instead of scrolling away, with a height of 64px. On the left, state clearly how many cases there are right now (currently 6 — the German \"6 Projekte\" is fine); leave the right side empty for now, since the next step is to put filters there. When the window narrows, don't let the cards get squashed: at around a thousand pixels it should automatically become two columns, at phone width one column, and no horizontal scrollbar at any point."

   "operator": "repair",
   "request": "There's another problem we have to fix at the same time: the floating capsule nav at the bottom of the page. It used to be that whichever item I clicked got a bright yellow pill background with dark text, but now all three words look identical and you can't tell which section you're in — a colleague thought the nav was broken. Please restore it to how it was — the current item is a yellow-background dark-text capsule, the other items stay light-colored text, and hovering turns them yellow. Don't accidentally mess up the case grid and sticky toolbar you just built."

   "operator": "wire up data",
   "request": "The case studies now need to go fully live. Ops sent over the list: forty projects in total, grouped by industry, with three numbers after each project — launch year, duration (weeks), budget (in k€): Kultur — Bautz Festival 2021/14/38, Stadttheater Hemer 2019/9/24, Sauerlandpark Sommer 2022/6/15, Klangraum Lüdenscheid 2023/12/32, Museum Nachtschicht 2018/8/21, Festivalfunk RMP 2024/10/27, Kulturbüro Schriever 2025/7/19; Gesundheit — ehex 2022/26/96, curenect 2023/18/64, Praxisportal Alberts 2020/11/29, Rezeptbrücke 2021/16/48, Klinikfinder NRW 2024/22/75, Pflegeatlas 2019/13/36; Energie — Mark-E Direkt 2021/20/60, Solarrechner KCX 2022/10/40, Windpark Cockpit 2024/24/80, Netzampel 2025/30/120, Ökostrom Wechsler 2019/15/50, Speicherplaner 2018/9/30; Handel — Stegermeister Shop 2020/17/55, WGB Werkzeug B2B 2021/21/70, Radolid Katalog 2022/12/34, Selbstauslöser Store 2023/8/22, Hotel Vierjahreszeiten Buchung 2019/14/41, IMS Ersatzteile 2024/19/58, Schmale & Raabe Shop 2025/11/31, Clee Concept Store 2022/6/18; Bildung — Zentrum für Klimaforschung Niedersachsen Wissensportal 2023/16/52, Campus Kompass 2018/10/26, Lernpfad Sauerland 2021/7/20, Schulportal Hemer 2020/13/37, Mensa Now 2024/5/12, Alumni Hub 2025/18/56; Industrie — David&Goliath 2019/12/33, Bautz Industrie Intranet 2022/23/78, Logowall Maschinenbau 2020/15/44, Sensorik Dashboard 2023/28/99, Werksführung VR 2024/9/25, Instandhaltung Mobil 2025/20/62, Zulieferportal RMP 2018/11/28. Skip images for now — make all forty into uniform info cards: project name, colored industry tag, year, duration and budget must all be visible on the card face; without images the cards get shorter, uniformly 260 tall, with the same column count and 30px gap. One special note: the original six cases (Bautz Festival, ehex, curenect, David&Goliath, Mark-E Direkt, Zentrum für Klimaforschung Niedersachsen Wissensportal) had German subtitles and \"Case ansehen / Website ansehen\" link copy that are signed-off public copy — after the redesign they must stay on their respective cards; the 34 new projects don't need either. Industry colors follow design: Kultur #EE8442, Gesundheit #2BBE7A, Energie #EE7A3B, Handel #54809B, Bildung #A9D2D4, Industrie #979797. Fill the empty right half of the toolbar from the previous step: an industry filter (with \"Alle\"), a year filter (with \"Alle\", years 2018 to 2025), and a sort (default is the order given in the list above, plus budget high-to-low, budget low-to-high, and duration shortest-to-longest). The stats line on the left half must update in real time with the filter: how many projects match, the total budget of those projects in k€, and the average duration in weeks (truncate any remainder). Show 9 cards per page, with previous/next and the current page number below; changing any filter goes back to page 1. If a combination yields no projects, don't give me a blank area — write a German message telling the user there are no results, and the stats line should honestly show 0, with the pager buttons not clickable in that case. One project name in the list is especially long — make sure it doesn't burst out of its card."

  {
   "operator": "restyle",
   "request": "Last is the brand team's new \"day version\" palette: the site needs to switch between the night version and the day version, with the toggle in the bottom capsule nav (alongside the three nav words), still defaulting to the current night version. Day version: the page background becomes paper white #FDFBF4, headlines and body copy are all ink blue #14212C, and yellow #FFD401 is kept only for buttons and \"currently selected\" highlights. The night version must stay exactly as it is — still dark blue #192C3A with yellow text. The switch must apply site-wide, including case cards, the toolbar and the stats line. Two things to stress: the six industry colors are industry identity colors, unrelated to the skin — they must look identical in both modes; and don't mess up anything built earlier — it's just a skin change, so the current filter, sort, page number and those stats numbers must not change, and the nav must still show \"where I am\" at a glance. After refreshing, the user should still be on the skin they just chose."

Also append .floating-nav .nav-item.is-active:hover { background: transparent; color: #ffd401; } so hover behavior doesn't reveal the original highlight either. Do not modify the logic in App.jsx that adds the is-active class name (the class must still be correctly attached to the current item), do not change the styles, layout or behavior of any element outside the nav, leave no comments or TODO text, and produce no console errors or warnings at runtime."
