description	Takram Soft Tech (东方柔光科技) — soft, Eastern-philosophy tech decks adapted from the ppt-takram showcase of 花叔 (alchaincyf)'s huashu-design. Warm rice-paper canvas (#F5F0EB), sage green + warm gray + one gold, Noto Serif SC display headings mixed with Inter labels, rounded translucent data cards, and the signature device: SVG data visualization treated as an art piece — multi-series overlaid radar charts on hand-drawn dashed grids with "Fig. NN" plate annotations. Use when the user wants a gentle, nature-toned tech deck, product briefing, benchmark report, 柔和科技感, 自然色系 PPT, or "数据可视化当艺术品" presentations.

Takram Soft Tech · 东方柔光科技

Produce a single-file, soft nature-toned tech deck. You are a research studio designer working in HTML: every chart is composed like a museum plate, every color is borrowed from moss, paper and dusk. The visual system, canvas contract, and navigation runtime are locked by example.html. Start from example.html, replace content only — do not rewrite the design or the script. Do not introduce any color or font outside this spec.

Adapted from the ppt-takram showcase of huashu-design by 花叔 (alchaincyf), MIT licensed. The upstream file is a single benchmark page; this plugin extends it into a full multi-section deck while preserving its DNA: data visualization treated as an art piece.

Hard spec (locked — violating any line is a regression)

Canvas & runtime

• One <div id="stage"> fixed at 1920 × 1080 px, centered with position: fixed; top: 50%; left: 50%; a fit() function applies translate(-50%, -50%) scale(min(innerWidth/1920, innerHeight/1080)) on load and resize. All inner layout in px — the scaler owns responsiveness.
• Each page is one <section class="slide"> inside #stage with a data-screen-label="01 封面"-style label; exactly one slide carries .active. This is an all-light style — there are no dark pages; rhythm comes from density alternation, not theme swaps.
• Navigation (keep the script verbatim): ←/↑/PageUp previous, →/↓/Space/PageDown next, Home/End first/last; #/N hash routing (1-indexed) read on load + hashchange, written via history.replaceState; click left third = back, rest = forward; fixed counter pill bottom-right, key-hint bottom-left. No external JS, no build step — the file must open inside a sandboxed iframe via file://.

Design tokens (:root — keep the names, re-theme values only)

Token	Value	Role
--paper	#F5F0EB	warm rice-paper page background
--ink	#2D3436	heading ink
--body	#3A3A3A	body ink
--green	#6B8F71	sage green — the primary accent
--green-2	#7D9B72	lighter sage (delta pills, fills)
--sage	#A8B5A0	pale sage (labels, washes, flow lines)
--gold	#D4A574	the only warm accent — 2nd data series
--gray-warm	#C8C2B8	warm gray — 3rd data series, captions
--gray-line	#D4CFC6	delicate axis / rule lines
--gray-dash	#DDD9D2	dashed grid circles
--gray-bg	#E8E4DC	faint outermost rings
--muted	#615C54	secondary text (warm ink, WCAG AA on paper)
--faint	#736D64	tertiary captions (warm ink, WCAG AA)
--card	rgba(255,255,255,0.6)	translucent card background
--card-line	rgba(168,181,160,0.18)	card hairline border
--serif	'Noto Serif SC', 'Songti SC', serif	display headings, quotes, insight text

Fonts come from one Google Fonts @import (Inter 300–600 + Noto Serif SC 300–700) — the only external reference allowed. No purple, no blue, no neon, no pure black, no gradients other than the two locked radial washes.

Signature devices (the visual DNA — every deck must show them)

1. Data visualization as an art piece: charts are inline SVG composed like museum plates — concentric dashed-circle grids (--gray-dash, stroke-dasharray="2,6", decreasing stroke-width outward-in), delicate 0.5px axis lines, tiny hollow endpoint circles, faint scale numbers, and a 3-series overlay: green polygon prominent (stroke 2, dot r=6 with halo ring), gold secondary (stroke 1.2, dot r=3.5), warm-gray tertiary (stroke 1 dashed, dot r=2.5). Value callouts use thin annotation lines
   • 14px/600 green numerals. Every plate signs off with a right-aligned 8–9px Fig. NN — Title caption in --gray-warm.
2. Soft radial washes: every slide's ::before carries the two locked radial-gradients (sage at 20%/50%, warm gray at 80%/30%, ≤8% alpha) — the page must breathe, never be flat white.
3. Rounded translucent cards (.soft-card): 16px radius, rgba(255,255,255,0.6) fill, --card-line hairline border, and a 32px × 2px sage tick at top-left (::before). Value typography: 38–44px weight-300 numerals with a smaller green unit span; deltas in a rounded sage pill with a tiny SVG triangle (gold pill allowed once per page for a special callout).
4. Hairline masthead on every page: 64px strip, bottom border rgba(107,143,113,0.15); left = green dot + 11px/500/3px-tracking uppercase deck name; right = 10px/400 --faint section label. Footer: 11px faint credit line bottom-left, Fig./Sec. note bottom-right. Page numbering lives only in the runtime counter pill.
5. Serif/sans mixing discipline: headings, quotes and insight prose in --serif weight 400–500 (never 700+ display bombast); all labels, numerals, units and captions in --sans. English subtitles are 15–18px weight-300 --muted prose under Chinese serif titles.
6. Badge & insight: rounded-24px pill badge (green dot + 13px green label on 8% green fill) and the .insight card (10px uppercase sage label + serif 17px/1.9 finding text) for key takeaways.

Layout enumeration (use 5+ per deck, never one layout everywhere)

Layout	Role
cover	left serif display title + badge, right oversized dashed-ring SVG art
contents	serif rows + green index numbers separated by sage hairlines
philosophy	one 60–70px serif claim + 3 soft-cards
big-number	240–280px weight-300 numeral + green unit + hairline stat row
radar (the master)	480px left panel (kicker/serif title/badge/insight/credit) + right radar plate + 3 metric cards — preserve this two-panel grid from upstream
diagram	SVG flow/architecture plate: dashed clusters, sage dashed flow paths, gold middle node, green terminal node
metrics-grid	2×3 soft-card grid with delta pills
quote	centered serif 52px quote, gold SVG quote marks, key phrase in green
roadmap	hairline timeline, dots graded --gray-warm → --sage → --green-2 → --green (last with halo)
closing	centered serif CTA over faint concentric rings + badge

Typography & scale (read from 10 meters)

• Serif display: cover 90–104px, section titles 44–66px, weight 400–500, letter-spacing ~1px, line-height 1.35–1.65. Hero numerals 240–280px weight 300 with negative tracking.
• Labels: 10–13px, weight 500, letter-spacing: 1.5–3px, uppercase — the connective tissue of the style. Body/captions 13–18px weight 300, line-height 1.7–1.9.
• Chinese copy uses 「」 quotes; bilingual pages put Chinese serif first, English weight-300 sans second.

Rhythm & discipline

• Default 10 pages (8–11 allowed). Alternate density: text page → chart plate → whitespace/quote page. At least one radar/diagram art plate per deck — it is the reason this style exists.
• Color budget: green is the protagonist; gold appears only as the 2nd data series, quote marks, or one special delta pill; warm gray is the 3rd series and all chrome. Never promote gold or gray to a heading color.
• No emoji, no icon fonts, no shadows heavier than the locked drop-shadow(0 4px 20px rgba(0,0,0,0.04)), no border heavier than 1px except SVG data strokes, no Chart.js/mermaid — all charts are hand-laid inline SVG.
• Real content only — the user's actual numbers; missing data gets an honest <!-- 待用户提供 --> placeholder, never invented statistics. (The seed deck's 「青屿/QINGYU」 data is fictional demo content and must be fully replaced.)

Workflow

1. Clarify once: topic, audience, page count, and which comparison or dataset becomes the radar/diagram art plate — this style lives and dies by its chart plate; pick it before writing any page.
2. Copy example.html, retitle, then replace each section's content following the layout enumeration. Keep masthead/footer chrome, washes, token names, and the script intact. Re-theme by changing token values only — and only if the user's brand genuinely demands it; the sage/gold/warm-gray triad on rice paper is the identity.
3. For ≥ 5 pages, showcase first: build the cover + the radar master page, confirm the grammar, then batch the rest.
4. Radar geometry: when axis values change, recompute polygon points as (cx + r·sin(θ), cy − r·cos(θ)) with r = 220 · value/100, θ ∈ {0°, 120°, 240°} around (280, 280) — printed values and polygon shape must agree proportionally.
5. Self-check before delivery: arrow through every page; counter and #/N hash stay in sync; no overflow beyond 1920×1080; every chart plate has its Fig. NN caption; only the three series colors appear in any chart; no leftover demo (「青屿」/"QINGYU") text; grep for TODO.
