NON-NEGOTIABLE RULES / WINDOWS + BILINGUAL + OBJECT + MEDIA + KNOWLEDGE
01Structure before expression. 先建立信息秩序,再允许视觉表达。
02Space is active. 空白是实体,不是没用完的位置。
03One gesture per page. 每页最多一个明确设计动作。
04Thin, not merely small. 追求轻薄与低重量,而非单纯缩小。
05Asymmetry inside order. 局部偏移必须发生在稳定比例之内。
06Information never becomes decoration. Metadata、线、颜色、symbol 都必须有语义。
07Forbidden by default: rounded cards, gradients, glass, glow, giant hero type, marquee, parallax, soft shadow, dashboard aesthetics.
08Scrollable fields have no visible scrollbar. Use spatial continuity or a quiet numeric coordinate for orientation.
09Bilingual text aligns by semantic paragraph pair, never by forced line-for-line matching.
10English and Chinese keep script-specific measure and leading; visual equality does not mean identical metrics.
11On narrow screens preserve local translation pairs: EN₁ → 中文₁ → EN₂ → 中文₂, not language-separated blocks.
12Object before interface. 在对象页中,branding、UI 与操作必须退居对象之后。
13Spatial priority precedes typographic priority. 先用位置、留白与轴线建立 hierarchy,再考虑字号与 weight。
14Grid structures the collection; objects do not receive card containers by default.
15Keep metadata marginal and compressed in indexes; decompress technical detail only on the object page.
16Neutral media fields should dissolve image rectangles into the page whenever the object permits.
17Filters read as taxonomy/index, not as a dashboard of pills, dropdowns and boxed controls.
18One dominant operation per object page. Functional black is reserved for commit / enter / execute.
19Use inline bilingual metadata for short fields; use parallel bilingual prose for extended descriptions.
20Major work, minor study and fragment remain inside the same institutional grammar.
21SSENSE influence is limited to product listing/detail logic; never import its homepage, editorial or commerce skin as LAB identity.
22Still before motion; motion before immersion. 更深的媒体状态必须由更明确的观察需求触发。
23A 3D model is an observation mode, never a background effect or proof of technical sophistication.
24Object scale is finite. Larger screens create more void instead of indefinitely enlarging the object.
25One viewport, one active temporal medium. Grids remain still until a single item receives explicit focus.
26Object pages orbit around the object; space pages begin from authored camera anchors. Free exploration is exceptional, not default.
27WebGL appears only after intent. No homepage or object grid mounts multiple persistent 3D canvases.
28Photography, motion and model must reveal different information. Repetition across media is visual noise.
29Media interface vocabulary stays singular and institutional; bilingualism belongs to content, not every viewer control.
30The institutional frame remains visually dominant over the media interface, including inside spatial mode.
31Master assets and web payloads are separate systems. Preserve high-quality sources; publish optimized GLB / texture tiers.
32No amount of technical capability justifies breaking the quietness of the page.
33Knowledge documents use normal page flow, not nested reading panels. Sticky navigation may orient; it must not imprison the prose.
34Monolingual knowledge pages use 18/54/28; bilingual knowledge pages use 18/41/41. These are canonical document grids, not universal page grids.
35The marginal field carries evidence only: definitions, figures, citations, equations, revisions and cross-references — never generic widgets.
36Sections are semantic structural objects. H1 is generated from metadata; H2 and H3 carry the authored hierarchy.
37Figures declare a semantic mode — inline, margin, spread, compare, sequence or media — rather than receiving arbitrary author-defined widths.
38NOTE / RULE / EXAMPLE / CAUTION are typographic structures with hairlines, not colored cards or icon-driven components.
39Markdown carries meaning; CSS and LAB components carry appearance. Raw presentational HTML and inline styling are non-canonical.
40Canonical knowledge compilation is MD → validated AST → semantic components → HTML. Regex/string templating is not the document architecture.
41Frontmatter schema controls document type, status, language, version and cross-reference behavior. Authors do not invent metadata ad hoc.
42Human-authored and agent-authored documents must be structurally and visually indistinguishable after the same build and lint pipeline.
43Fixed Document and Floating Note are separate window classes: the former is modal authority; the latter is non-modal provisional thought.
44Floating notes drag only by a dedicated handle, raise on focus, remain clamped to the workspace and may coexist without creating a backdrop.
45On mobile, free-floating windows collapse into an ordered note stack or sheet; overlapping drag UI is desktop-only.
46Long-form prose is justified with the final line left-aligned. English and Chinese use independent justification and leading rules.
47Knowledge columns are separated by whitespace and alignment, not persistent vertical dividers.
48Marginal figures and footnotes align to the paragraph that invokes them. Figure inspection opens a media preview without document-object shadow.
49In bilingual documents, shared figures span both language columns between semantic pairs; language-specific figures stay inside their language column.
50Code syntax highlighting is grayscale-only; chromatic color remains reserved for document-level annotation and signal states.
51Media distance must be explicit: still = whole, detail = surface, model = oblique object inspection, space = inhabitable relational sequence.
52English justified prose may widen its measure or enable hyphenation when narrow columns produce uneven word spacing.
53Overall page composition is governed by mass, counterweight, reserve void and a single dominant orientation axis. Components do not self-author page composition.
54Charts, formulas and mermaid diagrams inherit the LAB grayscale, hairline and metadata syntax. Quantitative graphics are evidence, not decorative illustration.
55Figure modes must be legible as spatial rights: inline, margin, spread, compare, sequence and media each imply a distinct relationship to prose.
56Author-facing directives remain human-readable shortcuts. If a new writer cannot understand what a directive does, the authoring surface is too technical.
57Canonical production type roles are fixed at approximately 10 / 11 / 13 / 15 / 20 / 24px; larger typography is exceptional rather than a default hierarchy tool.
58English justification is conditional on adequate measure. Widen the column and enable hyphenation before tolerating visibly uneven word spacing.
59Long-form paragraph rhythm is defined by measure, leading and semantic spacing: paragraph gaps stay compact; section and chapter gaps carry the major pauses.
60Chronology is represented as a temporal ledger: time coordinate, event, and aligned evidence. Decorative vertical timeline spines and status-pill roadmaps are non-canonical.
61Milestone history, development log and machine/session trace use different information densities while sharing the same temporal coordinate language.
62The font palette is intentionally narrow: institutional sans, CJK sans companion, technical mono, document mono and a formula-only math face. Decorative accent families are non-canonical.
63Neue Haas Grotesk / Helvetica lineage is the Latin institutional reference; Source Han / Noto Sans CJK lineage is the canonical Chinese companion. Fallbacks may change metrics but not semantic roles.
64Pale micro-typography is achieved through ink value and opacity at 400 weight before resorting to ultra-light glyphs.
65Weight 300 is restricted to non-critical display text at approximately 18px or larger. Metadata, navigation, body prose, tables and captions remain 400 or above.
66Technical mono is reserved for code, metrics, IDs, timelines, coordinates and traces; document mono is reserved for notes, manifesto, memo and floating-document voice.
67Weight 500 indicates structural emphasis; 600 is a brand exception; 700+ and synthetic bold/italic are non-canonical.
68A new font family requires a new semantic role. Departments, projects and campaigns may not introduce temporary accent fonts merely to create visual variety.
69Technical memo voice defaults to the Letter Gothic / IBM office-technology lineage; Courier is reserved for archival, authorial or manifesto-like document voice.
70OCR-B is a machine/archival accent face for short labels and identifiers only; it is never a long-form memo or prose family.
71Markdown never selects typography directly. Semantic syntax maps to canonical roles: document title, section, body, quotation, technical mono, footnote, list and directive.
72Markdown strong maps to weight 500, not 700; English emphasis uses true italic while Chinese remains upright.
73The design-system preview itself must obey the same production typography and paragraph rules it documents.
74Scroll fields and sticky metadata may use solid local backing where necessary, but gradient fades at content edges are non-canonical.
75At stacked medium widths, the symbol field keeps a bounded local scroll region while the intro document resumes normal page flow; copyright may not become a full-width overlay banner.
76Guidance-column English is left-aligned by default. Justification is reserved for explicitly controlled long-form reading measures where word spacing remains stable.
77All manual sections share one guidance measure and a visible hierarchy: 18px section guidance title, 13px explanatory body, 11px rule/detail text, and 9px registry labels.
78Letter Gothic is the continuous internal engineering-memo voice; OCR-B is the registry/identifier/timestamp/revision voice. OCR-B never sets paragraph prose.
79Bilingual alignment is two-level: section/chapter pairs share a top anchor; natural paragraphs inside each section flow independently until the next section reset.
80Every specimen in this manual must state both mandatory behavior and prohibited behavior. Revision history may explain change, but implementation guidance must remain timeless and absolute.
81Guidance headings are bilingual with Chinese as the primary line and English as the secondary line. Core mandatory/prohibited guidance is bilingual in every specimen.
82The symbol-field study title/copyright and scroll coordinate occupy one sticky coordinate bar at the same vertical level; neither waits at the end of the scroll field.
83Homepage explanatory prose is bilingual, concise and institutional. English and Chinese carry equal semantic authority rather than primary/secondary translation status.
84Every specimen guidance panel uses two equal language columns: Chinese and English carry the same mandatory/prohibited structure. Neither language is styled as a subtitle of the other.
85Extended commentary is secondary to the canonical bilingual rules and may be collapsed under DETAIL / 详细说明 to protect column rhythm and hierarchy.
86The homepage framework uses the canonical 18/41/41 bilingual knowledge logic for Foundation, Object, Media and Knowledge. Labels occupy the 18% rail; English and Chinese occupy equal semantic columns.
87The symbol-field coordinate bar is fixed to the lower edge of the bounded field while the glyph plane scrolls independently behind it.
88At desktop widths the opening frame occupies exactly the available viewport below the 48px header; the first design-system specimen begins at the next viewport boundary rather than bleeding into the opening frame.
89Micro-events belong to a finite palette: displacement, reveal, rule extension, state transfer, focus aperture, logical toggle, tactile lift and boundary anomaly.
90Ordinary micro-events use approximately 2–6px amplitude and 120–220ms duration; 320ms is the normal ceiling unless the interaction is a genuine page/mode transition.
91Only one dominant micro-event may operate in a local view at a time. Multiple simultaneous transforms, glows, scales and morphs are non-canonical.
92Meaningful hover interactions require keyboard-focus or click/touch equivalence. Accessibility states may be visually quiet but must remain unambiguous.
93The micro-event vocabulary is organized as a finite periodic system across Signal, Vector, State, Topology, Object and Boundary families; new events must belong to a defined family rather than becoming ad-hoc effects.
94B/Reveal, C/Extend, D/Transfer, F/Toggle, G/Lift and H/Boundary are canonical core micro-events. A/Settle is the canonical subtle node-settling animation.
95Desktop Floating Notes use one canonical outer geometry only: 4:3 landscape at 288 × 216 in the reference preview. Free resizing and alternate ratios are non-canonical.
96Floating-note content adapts inside the fixed 4:3 frame through internal vertical scrolling and semantic structure; outer geometry does not change according to content type.
97Space Plate #39 and Depth-on-Demand #40 form one intentional linked demonstration: #39 is the pre-entry authored frame and #40 is the post-intent spatial mode.
98Media-distance diagrams must make observer position explicit: Still/Detail/Model remain external observations; Space crosses the boundary into an internal circulation field.
99Object-model explanatory views use an upper-right approximately 45-degree oblique view when thickness, reverse faces and topology must be legible.
100Media detail plates reserve the central field for actual media. Short bilingual metadata stays marginal, controls stay concise, and long bilingual explanation sits below the media rather than replacing it.
101All Floating Note bodies support internal vertical scrolling while scrollbar chrome remains visually hidden.
102Long justified prose preserves canonical type size and leading inside the fixed 4:3 note; overflow is solved by scrolling, never typographic compression.
103Multiple Floating Notes may coexist only when each preserves the same 4:3 outer geometry, reinforcing a coherent desk-like institutional field.
1041920×1080 at normal browser/OS scaling is the Standard Desktop typography baseline; all production component scales are calibrated against this density.
105Expanded Desktop activates at approximately 2200 CSS px viewport width and raises core typography by roughly 10–15% while increasing spacing less aggressively.
106Perceptual-density breakpoints are based on CSS viewport dimensions, not physical monitor resolution, DPR or named device classes.
107Functional typography has an absolute floor of 9px in Standard Desktop and 10px in Expanded Desktop. Smaller values are non-canonical for production UI, metadata and diagram labels.
108Compact Desktop preserves the Standard typography floor and resolves limited space through composition, reduced gaps, fewer simultaneous columns or bounded local scroll fields rather than smaller type.
109Expanded displays primarily gain void. Typography may grow 10–15%, spacing approximately 5–8%, and media/object scale 0–5%; the interface must not behave like a uniform browser zoom.
110Windows/macOS display scaling is allowed to cooperate with the CSS-density system: a 2K screen rendered near 2048 CSS px under 125% OS scaling remains in Standard mode instead of receiving duplicate enlargement.
