Chat grammar follow-ups: seat the dark prompt bubble, drop the UPDATE eyebrow#249kateebonner wants to merge 3 commits into

The inverse grammar stays (the user's words are the INVERSE of the ground), but its dark realisation was pure grey-50: the only 100%-luminance surface in the UI, at up to 85% column width — a lamp, not a bubble. Dark ink on a light ground doesn't emit; a white panel on a dark one does. New role tokens in design-polish.css (--prompt-bubble-bg/-ink): light is the site's ink bubble verbatim; dark mixes 15% of the page ground into the inverse (#dcdcdc on stock dark — ≈13:1 on the ground, ≈11:1 under its own ink). The bubble, its in-bubble file/agent chips, and the pinned last-prompt ghost all consume the tokens — one grammar on every surface; message-part.css falls back to raw inverse for consumers without the app skin (enterprise, storybook). Verified live on :3004 against the :4096 server: dark bubble computes to color(srgb .8629…) = #dcdcdc on #080808, light stays #000/#fafafa. oxlint (baseline: 1 pre-existing error), tsgo -b clean.
The rail label exists to name steps whose content doesn't open with its own title. For reasoning that's real information; for prose the words ARE the step, and captioning every one "UPDATE" was pure repetition — one walkthrough session wore seven of them. Reasoning keeps its label; prose now leads with itself, and the measured dot-on-first-line (69c98ee) re-seats the rail dot on the prose automatically. Verified live on :3004: sessions that rendered 2/7/3 UPDATE labels render zero, REASONING unaffected. oxlint (baseline), tsgo -b clean.

MDN CSS word-break break-word deprecated overflow-wrap anywhere equivalent semantics
💡 Result:
The CSS value word-break: break-word is officially deprecated [1][2]. It is maintained solely for legacy compatibility, and developers are advised against using it in new stylesheets [3][4]. The functionality previously provided by word-break: break-word is now better handled by the overflow-wrap property [5][6][3]. Specifically, overflow-wrap: anywhere is the modern, standard-compliant equivalent [1][7][3]. Key points regarding the semantics and differences: 1. Deprecation Status: The W3C CSS Working Group has marked word-break: break-word as deprecated [8]. Some discussions have even proposed normative prohibitions against its use in new code to discourage reliance on this non-standard behavior [4]. 2. Semantics and Behavior: - word-break: break-word was originally introduced to provide a way to break long words while still behaving similarly to normal word-break behavior in other contexts [5][6]. - overflow-wrap: anywhere is designed to allow lines to break at any point if necessary to prevent overflow, essentially providing the robust wrapping behavior developers sought from the deprecated keyword [7][5]. 3. Intrinsic Sizing Differences: - A technical distinction exists regarding how these values interact with min-content intrinsic size calculations [5][6]. - overflow-wrap: anywhere allows the browser to break lines at any point, but importantly, it does not consider these potential break points when calculating min-content intrinsic sizes [7][9]. - In contrast, word-break: break-word does consider soft wrap opportunities introduced by the break when calculating min-content [8][5]. Because overflow-wrap: anywhere avoids the intrinsic sizing side effects of the legacy break-word value, it is generally considered the superior and more predictable choice for preventing text overflow in modern CSS layouts [7][5].

The 85% seat was still too bright in use (Kate). Same grammar, same tokens — only dark's mix moves: 30% of the page ground into the inverse instead of 15%, ≈#b9b9b9 on stock dark. Separation ≈9:1 on the ground, ≈8:1 under its own ink — comfortably above every floor.

Two follow-ups that landed on the #247 branch just after it merged.
Seat the dark prompt bubble at ~85% luminance (7b1ff4e). The inverse grammar stays — the user's words are the INVERSE of the ground — but its dark realisation was pure grey-50: the only 100%-luminance surface in the UI, at up to 85% column width. A lamp, not a bubble. New role tokens in design-polish.css (

The bubble, its in-bubble file/agent chips, and the pinned last-prompt ghost all consume the tokens; message-part.css falls back to raw inverse for consumers without the app skin (enterprise, storybook).Drop the UPDATE eyebrow on prose steps (2bfaeee). The rail label names steps whose content doesn't open with its own title. For reasoning that's real information; for prose the words ARE the step — captioning every one "UPDATE" was pure repetition (one walkthrough session wore seven). Reasoning keeps its label; the measured dot-on-first-line (#247) re-seats the rail dot on the prose automatically.
Verified live on :3004 against the :4096 server, both schemes: dark bubble computes to #dcdcdc, light stays #000/#fafafa; sessions that rendered 2/7/3 UPDATE labels render zero, REASONING unaffected. oxlint (baseline: same 1 pre-existing error), tsgo -b clean.
