   DƯỠNG SINH — trị liệu thảo mộc
   --------------------------------------------------------------------------
   CONCEPT
   Botanical apothecary: the page is laid out like the label of a herbal
   preparation — thin rules, small caps, weighed ingredient lists — and the
   hero pairs real treatment photography with a deep-sage reading
   surface and a cream recipe label.

   PALETTE (WCAG 2.2 — every pair computed, none assumed)
     --cream         #FBF8F0  page surface
     --oat           #F2EBDC  raised card / label stock
     --surface-input #FFFDF7  form field fill
     --ink           #2E3A2B  primary text      on cream 11.3:1 / on oat 10.1:1
     --ink-soft      #5C6355  muted text        on cream  5.9:1 / on oat 5.2:1
     --sage          #5F7256  links / accents   on cream  4.9:1
     --sage-on-oat   #546449  eyebrow on oat    5.4:1 on oat / 6.0:1 on cream
     --sage-deep     #2E3A2B  dark surface
     --clay          #9A5B41  accent labels     on cream  5.0:1
     --clay-deep     #7A442F  button fill; cream on it 7.3:1
     --sage-line     #D5D9CA  hairline rules — decorative only, never a control edge
     --sage-tint     #E8EADF  quiet fill (non-text)

     Control boundaries (WCAG 1.4.11, ≥ 3:1 required)
     --field-border        #8A8371  3.71:1 on --surface-input
     --field-border-hover  #7E7765  4.38:1 on --surface-input
     --btn-ghost-line      #7C8276  3.73:1 on cream / 3.02:1 on --sage-deep
     chip + menu-toggle edge   same --field-border  3.56:1 on cream

     On --sage-deep (#2E3A2B)
     --on-dark        #FBF8F0 11.3:1   --on-dark-strong #D6DCCB 8.5:1
     --on-dark-body   #C6CEBA  7.4:1   --on-dark-muted  #C3CBB4 7.1:1
     --on-dark-soft   #B9C2AC  6.5:1   --on-dark-faint  #A9B39C 5.5:1
     --hero-accent    #D9C9A8  7.3:1   --focus-dark     #E8B79B 6.6:1
     --on-hero-accent #2A3326  8.0:1 on --hero-accent

     On --surface-input (#FFFDF7)
     --placeholder    #6B7064  5.0:1   --danger #8C3A22  7.5:1

     Focus ring: --clay-deep #7A442F on light (7.3:1); --focus-dark on dark (6.6:1)

   TYPE
     Display  Cormorant Garamond 400/500/600 + italic
     Text     Nunito Sans 300–700
     display  clamp(2.85rem,6.6vw,5.4rem) / .97 / -.022em / 500
     h2       clamp(2rem,4.2vw,3.3rem) / 1.04 / -.015em / 500
     h3       clamp(1.5rem,2vw,1.75rem) / 1.08 / -.01em / 600 (Cormorant)
     body     1.0625rem (17px) / 1.68 / 0 / 400
     prose    1rem (16px) — the floor for anything a reader must read
     small    .95rem (15.2px) / 1.5 — nav and buttons
     meta     .875rem (14px) / 1.4 — tabular rows, hints, chips
     label    .78rem (12.5px) / 1.35 / .16em uppercase
     Six steps for body copy: 12.5 / 14 / 15.2 / 16 / 17 / h3. Nothing between
     them. The brand word and footer word are the only display outliers.

   LAYOUT
     A 12-column label grid on a 1180px measure. Everything is a printed
     block: a rule above, a rule below, a designation in the left margin.
     Hero = deep-sage copy + a treatment photograph and recipe label.
     Sections alternate cream / oat / deep sage to give the page a spine.
     One section beat (--section-y) and one head beat (--head-gap) set the
     whole vertical rhythm.

   SIGNATURE MOTION
     The hero headline rises through a short translate mask, always painted.
     Photography stays still; the treatment filter and 680ms batch reveals
     provide the quieter secondary motion.

   PORT (portfolio)
     "Liệu trình" — 8 treatments, 4 categories + Tất cả, live count, empty
     state, URL-synced via ?cat=.
