@@ -50,6 +50,14 @@ Five content/behaviour mechanics keep the fleet from reading as machine-generate
 - **Usernames read like nerd handles, not real names.** Bots do NOT sign up with faker person names; they pick devRant/Hacker-News-style handles. Two layers, LLM-first with an offline fallback: (1) `llm.generate_handle_candidates(persona)` asks the model for ~8 distinct handles grounded in the persona and its `SEARCH_TERMS` interests (tech nouns, leetspeak, adjective+noun, creatures, short word+number), each run through `handles.sanitize_handle`; the pool is cached on `BotState.handle_candidates` and consumed by `_next_handle()`. (2) `handles.make_handle(interests)` is the pure, offline algorithmic generator (curated word banks + probabilistic leetspeak + number/separator/casing decoration, persona-seeded from `SEARCH_TERMS`), used as the fallback whenever the LLM pool is empty or a signup collides. Both layers emit only `[A-Za-z0-9_-]`, 3 to 20 chars (the old `first.last` styles silently failed signup validation, which rejects dots). On a third signup retry a random number is appended to bust collisions. Word banks and tuning constants live in `services/bot/handles.py`; never reintroduce faker person-name handles.
 - **Bots engage each other, and threads deepen.** `ArticleRegistry` allows up to `max_per_article` holders per article (admin `bot_max_per_article`, default 2), each with a **distinct category** (stored as `holders: [{bot, category, time}]`; old `{bot, time}` rows are normalized on load), so two bots can post different angles on the same trending news - which gives them each other's posts to discuss. A holder ages out after `ttl_days` (admin `bot_article_ttl_days`, default 7). `_engage_community()` (called once per normal/deep session after notifications) goes to `/feed?tab=recent|trending`, ranks non-own posts with a preference for `known_users` authors, opens one, comments, and replies into the comment thread. The on-post reply-to-comment probability is also raised so multi-bot threads actually form. `reserve(title, owner, category)` is idempotent per owner and enforces the same distinct-angle / max-holders rules as `reserve_unused`.
 
+## Profile disclosure signal (soft bot marker)
+
+Every bot's profile must carry a vague, never-literal hint that the account is synthetic, anchored on `config.HOME_URL` (`https://devplace.net`). The deterministic marker is the host `devplace.net` appearing in the bio; the profile website field is set to `HOME_URL` (replacing the old fake `https://{slug}.dev`). Three layers, all funneled through the single `_update_profile` choke point (so the procedural path and the AI-decision `update_profile` action both comply):
+
+- **Generation:** `llm.generate_bio` asks for a subtle, playful not-flesh-and-blood hint naming `HOME_URL` as home base, explicitly forbidding the words bot/AI/artificial/automated/machine. `generate_profile_fields` returns `HOME_URL` as the website.
+- **Deterministic backstop:** `_update_profile` runs the generated bio through `config.ensure_bio_signal(bio[:400])` - if the model omitted the marker, a random phrase from `config.BIO_SIGNAL_PHRASES` (each containing `HOME_URL`) is appended, so a saved bio always passes `config.bio_has_signal`.
+- **Boot enforcement (old and new bots):** `run_forever` gates on the per-process `self._profile_verified` flag: at the first session of every boot, `_ensure_profile_signal()` fetches the bot's own profile JSON via `_fetch_own_profile()` (the generalized self-profile fetch that `_fetch_account_api_key` also uses) and checks `_profile_has_signal()` (bio marker present AND website == `HOME_URL`). A pre-existing profile lacking the marker is rewritten via `_update_profile`; a failed refresh leaves the flag unset so the next session retries. Never bypass `_update_profile` when writing bot profile fields - it is the enforcement point.
+
 ## AI-driven decisions and identity cards (`bot_ai_decisions`)
 
 Opt-in mechanic (off by default; full design and cost model in `aibots.md`). When `bot_ai_decisions` is on, a bot replaces the procedural action cascade with one LLM decision call per page, driven by a unique AI-generated identity. **Do not regress the grounding and the kill-switch fallback.**

+# CSS system (`devplacepy/static/css/`)
+
+This file documents the CSS conventions for every stylesheet in this directory. Claude Code auto-loads it when a file under `static/css/` is read or edited. The member-facing style guide lives at `/docs/styles*.html`; keep both in sync when a convention changes.
+
+## Tokens (`variables.css` is the single source of truth)
+
+- **Never hardcode a themable value.** Colours, spacing (`--space-xs`...`--space-2xl`), radii, shadows, fonts, layout measures, and z-indexes are always `var(--token)` references. A missing value means adding a token to `variables.css`, not inlining a literal.
+- **Never give a global token a fallback.** `var(--accent)`, never `var(--accent, #hex)`. A fallback silently masks a dead or misspelled token - the page keeps rendering from a value nobody maintains. This was a real bug class: `var(--topic-discussion, #ef4444)`, `var(--bg-code, #1a1a2e)`, `var(--accent, #6366f1)` referenced tokens that never existed and shipped a foreign palette via their fallbacks.
+- **Accent tints compose the channel token:** `rgba(var(--accent-rgb), 0.3)`, never a literal `rgba(255, 107, 53, ...)`. The raw accent literal exists only at its definition in `variables.css`.
+- **Status is semantic:** `--success`/`--warning`/`--danger`/`--info` for state, `--topic-*` only for topic badges. Never repurpose a topic token as a status colour or vice versa.
+- **One name per value.** Do not add alias tokens (`--space-base` and `--shadow-md` were removed for duplicating `--space-sm` and `--shadow`).
+
+## File-scoped palettes
+
+A feature with its own semantic palette defines it ONCE as a custom-property block at the top of its own stylesheet and references only those properties below: `devii.css` scopes `--devii-*` on `devii-terminal`; `isslop.css` scopes `--isslop-*` (solid + `-rgb` channel pairs for alpha composition) on `:root` (the file loads only on its own pages). Raw hex values may exist in exactly two places: `variables.css` and these blocks. A repeated hex or `rgba()` literal below a token block is a defect.
+
+## Stacking (`--z-*` tokens, two bands)
+
+Every `z-index` is a token from `variables.css`; literal values are forbidden except small local ladders (`z-index: 1`/`2`) inside an already-stacked component.
+
+| Band | Order (bottom to top) |
+|------|-----------------------|
+| Content | `--z-fab` 900, `--z-nav-overlay` 998, `--z-nav-panel` 999, `--z-nav` 1000, `--z-nav-drop` 1001, `--z-modal` 2000, `--z-popover` 2100, `--z-lightbox` 10000 |
+| Chrome | `--z-chrome-fw` 2147480000, `--z-chrome-devii` 2147483000, `--z-chrome-toast` 2147483400, `--z-chrome-menu` 2147483500, `--z-chrome-dialog` 2147483647 |
+
+The chrome band is **user-CSS-proof by design**: per-user injected CSS (the customization feature) must never stack above floating windows, the Devii terminal, toasts, the context menu, or confirm dialogs, so they live at the top of the integer range AND carry `will-change: transform` (the layer-promotion group in `base.css` - any new always-on fixed chrome element must join both). Toasts sit in the chrome band deliberately: they fire over open modals and stay clickable. The Devii tutorial-overlay ladder (2147483600-602 in `devii.css`) is an intentional local sequence between `--z-chrome-menu` and the devii avatar. A new stacked element picks the matching token or adds one between two stops in `variables.css` - never a number at the use site.
+
+## Breakpoints (exact, closed set)
+
+`@media (max-width: 1024px | 768px | 480px | 360px)` plus the capability/preference queries `(hover: none) and (pointer: coarse)` and `(prefers-reduced-motion: reduce)`. Nothing else. The historical one-offs (900/720/640/600/560/520) were consolidated by snapping each UP to the next canonical stop - snap-up is the required direction because collapsing earlier can never overflow, while snapping down leaves a viewport band the compact styles no longer protect. Element `max-width` values (content measures like `max-width: 720px` on an article column) are not breakpoints and are unaffected by this rule.
+
+## Reduced motion
+
+One global rule at the end of `base.css` collapses every animation/transition to `0.01ms` under `prefers-reduced-motion: reduce`. Its four `!important`s are the documented exception to the no-`!important` rule: a zero-specificity `*` selector cannot otherwise beat any class rule, and per-rule opt-outs would need editing every declaration. Durations are near-zero rather than `none` so JS `transitionend`/`animationend` handlers still fire. Pages add their own reduced-motion query ONLY when content must change (e.g. `deepsearch.css` stopping an indeterminate bar), never to re-disable motion.
+
+## Layout rules
+
+- Flexbox + CSS Grid with `gap` only; floats for layout are forbidden.
+- Approved page layouts and the shared shell are documented in `/docs/styles-layout.html`; a page supplies exactly one layout container inside `.page`.
+- Every fluid grid/flex column sets `min-width: 0`.
+- `!important` is allowed only for: the `.hidden`/`[hidden]` display utilities, the global reduced-motion rule, and the devii-avatar third-party-beating override. Anything else is a specificity problem to be fixed structurally.
+- Page-specific CSS lives in its own `static/css/*.css` loaded via `{% block extra_head %}`, never an inline `<style>` block; shared component styles live once (`components.css`, `feed.css` vote buttons) and are never redefined per page.

+Tokens are referenced bare, never with a `var(--token, fallback)` value, and all `z-index` values come from the stacking tokens. Feature-scoped palettes (`--devii-*` in `devii.css`, `--isslop-*` in `isslop.css`) are defined as custom-property blocks at the top of their own stylesheet; those blocks and `variables.css` are the only places a raw hex may appear.

 ## File organization
 
 `base.html` always loads the core set: `variables.css`, `base.css`, `components.css`, the syntax-highlighting theme, then `markdown.css`, `mention.css`, `attachments.css`, `lightbox.css`, `media.css`, and `engagement.css`. Page-specific stylesheets (`feed.css`, `post.css`, `gists.css`, `profile.css`, and so on) are loaded per page via the `{% block extra_head %}` block, so a page pays only for the CSS it needs.

-2. **One accent per view.** Exactly one primary action should carry `--accent`. Everything else is `--btn-secondary`/ghost.
-3. **Status and topic colours are semantic.** Do not use `--danger` for a non-destructive button or a topic colour as a background flourish.
-4. **Respect the text hierarchy.** Three shades only: primary, secondary, muted.
-5. **Surfaces step up, never sideways.** Page → card → card-hover. Do not place a card on `--bg-primary` without a surface token, and do not use `--bg-secondary` as a content card.
+1. **Never hardcode a colour.** Use the token: `color: var(--text-secondary)`, never `color: #b8a8d0`. If a value is missing, add a token to `variables.css` rather than inlining a hex. Accent tints at other alphas compose the channel token: `rgba(var(--accent-rgb), 0.3)`.
+2. **Never give a global token a fallback.** Write `var(--accent)`, never `var(--accent, #hex)`. A fallback silently masks a dead or misspelled token: the page keeps rendering, but from a value nobody maintains.
+3. **Feature palettes are file-scoped token blocks.** A page with its own semantic palette (the Devii terminal, the AI-usage grades) defines it once as custom properties at the top of its own stylesheet (`devii.css` scopes `--devii-*` on `devii-terminal`; `isslop.css` scopes `--isslop-*` on `:root`) and references only those below. Raw hex values may exist in exactly two places: `variables.css` and these file-scoped blocks.
+4. **One accent per view.** Exactly one primary action should carry `--accent`. Everything else is `--btn-secondary`/ghost.
+5. **Status and topic colours are semantic.** Do not use `--danger` for a non-destructive button or a topic colour as a background flourish. Status is always `--success`/`--warning`/`--danger`/`--info`; never repurpose a topic token for a status.
+6. **Respect the text hierarchy.** Three shades only: primary, secondary, muted.
+7. **Surfaces step up, never sideways.** Page → card → card-hover. Do not place a card on `--bg-primary` without a surface token, and do not use `--bg-secondary` as a content card.
 
 The reference below is rendered live from the tokens, so it always reflects the current theme.

+## Layering (z-index)
+
+Every `z-index` is a token from `variables.css`; a literal z-index value is forbidden. There are two bands:
+
+| Band | Tokens (bottom to top) | Purpose |
+|------|------------------------|---------|
+| Content | `--z-fab` (900), `--z-nav-overlay` (998), `--z-nav-panel` (999), `--z-nav` (1000), `--z-nav-drop` (1001), `--z-modal` (2000), `--z-popover` (2100), `--z-lightbox` (10000) | Normal page chrome: FAB, mobile nav, top nav, dropdowns, modals, autocomplete popovers, the image lightbox. |
+| Chrome (user-CSS-proof) | `--z-chrome-fw`, `--z-chrome-devii`, `--z-chrome-toast`, `--z-chrome-menu`, `--z-chrome-dialog` | Floating windows, the Devii terminal, toasts, the context menu, and confirm dialogs. These sit in the `2147480000+` range so per-user injected CSS can never stack above them, and each element is also layer-promoted with `will-change: transform`. |
+
+A new stacked element picks the token matching its role; if none fits, add a token between two existing stops in `variables.css` rather than writing a number at the use site. Local ladders inside an already-stacked component (small `z-index: 1` steps inside a card) stay literal.
+
 ## Acceptable and not
 
 - **Acceptable:** one layout container inside `.page`; CSS Grid for columns; `<aside>` for side columns; `min-width: 0` on the fluid column; sticky rails; cards built from tokens.

+**Respect reduced motion, globally.** One rule at the end of `base.css` collapses every animation and transition to a near-zero duration under `prefers-reduced-motion: reduce` (near-zero rather than `none`, so JavaScript `transitionend`/`animationend` handlers still fire). Pages never need their own reduced-motion query; a page-level one is only for content that must *also* change visually (for example stopping an indeterminate progress bar).
